Caliper Paint

• Got a simple one this week.  Your break calipers or drums are probably one of the first things to start to develop rust on your car.  The rust is ugly and noticeable, especially through certain types of alloy and aftermarket rims. 

• So lets get rid of this problem, the solution is as easy as 3 steps.

Before we get started, 

Picking Your Paint:  First off, get yourself a high-heat engine paint, or designated caliper spray paint from a local auto parts or hardware store.  There are multiple brands available, select colour, and consult application process and directions on the can before selecting which is best for you.  Another option we have used in the past is a regular, oil based rust paint.  It seems to hold up just fine.

Ideal Conditions:  Ideally you would like to completely remove your drum or caliper, and then paint them.  This allows for better accuracy, in painting only the parts you want, and eliminates over spray onto things like the disks, or your vehicle.

But, in the absence of time, as most of us need our vehicles, or just don’t want go through the effort of removing the parts, it can be done on the vehicle, just make sure to be meticulous when masking off the calipers and drums.  Also, make sure to cover your vehicle!

So let’s get started!

1.       Remove your wheel, and begin to remove all the surface rust and dirt from the drum or caliper you wish to paint.  We suggest using a wire brush for the surface rust, followed by sandpaper, the grit choice is up to you. Keep in mind, don’t rough it up, keep it as smooth as possible.  

 Remember, it’s not going to end up perfectly smooth but the paint will cover what rust or imperfections won’t come off.

(the bumper, bumper lip, and rims were at the body shop getting colour matched) 

2.     Proceed to cover the vehicle, masking off the areas to be painted and make sure everything else is covered. Spray paint travels further in the air than you think, and you will regret it when there’s over spray on your paint!  Also, make sure you cover your rotors, you don't want paint on your braking surface! We recommend removing them.

      We further covered the truck with a drop cloth, that met up with our newspaper, covering the entire vehicle. 

       

     

In the picture to the left, we were actually painting the outer edge of the dust cap as a red accent, but the process is the same.

You can see how the entire disk is wrapped with a garbage bag (very handy for this type of thing) and the remainder of the suspension covered with our newspaper drop cloth.

   

    

    3.  Make sure the surface is clean, and then paint!  Take your time and apply it in light coats, following the can directions appropriately. This will ensure proper bonding, and drying.  You don’t want your paint flaking do you?  Let it dry, and remount your wheel.   

      

After painting our dust caps as an accent, we painted the calipers black to clean it up.

     Guaranteed, your brakes don’t stand out for the wrong reasons anymore!

Strut Tower Bars

A strut tower bar (brace) (STB) is an aftermarket accessory for the suspension on a uni-body vehicle. The strut tower itself on these vehicles is basically a reinforced portion of the inner wheel well which contains the vehicle’s strut suspension system consisting of the spring and shock absorber. The vertical suspension’s load is transferred to the top of the vehicle’s strut tower; and because it isn’t directly connected to the main chassis rails of the vehicle, there is flex within the strut towers when cornering.

The strut bar is designed to reduce the flexing of the strut towers by attaching the towers together and reinforcing the structure between the two. This transmits the load from each strut tower through tension and compression of the strut bar, and helps to reduce the flexing of the chassis. Installing a strut tower bar on a unibody vehicle can make a noticeable difference when cornering.

Tools:

• Wrench(es)

Installation:

This is an extremely easy do-it-yourself, bolt-on modification to perform on your vehicle.

First, purchase a strut tower bar specifically designed for your make, model, and year of vehicle. These can be ordered from most custom automotive shops, Canadian Tire, or online. The model vehicle shown here is a ’95 Mitsubishi Eclipse, and we chose to install a front and rear strut tower bar. 

Test-fit your strut tower bar by placing it over top of the strut towers to ensure the bolts line up, and that you indeed have the correct bar.

Unscrew and remove the bolts on top of the strut tower bar (usually three), mount the strut bar into place, and replace the bolts.

It is that simple!

For our rear suspension, there were covers over top of the strut towers. If you don’t want to drill holes in the plastics of your interior, then you can leave the covers off. Or, make new covers using fiberglass (which we’ll teach you how to fiberglass in a future blog). We decided to take the easy route, and drilled holes of the right size and angle so the bar will fit through. 

Installation was just as straight-forward as the front. Unscrew bolts, mount, and screw bolts back on.

Now go for a ride, and feel the difference of your reinforced suspension.

Custom Mount Billet Grille

People love the aggressive look, and clean lines of a billet grille.  You can get these billet grilles in many designs and applications to fit most vehicles, and some come in both bolt over and cut out format.  You can pick them up online, or I'm sure your local auto shop would be glad to order you in one.  Easy enough to comprehend, the bolt over grilles mount with long hardware through your existing grill and fasten tight against it.  The cut out grilles involve a little more work, as you must first cut and remove your stock grill, and then install the billet grille with new hardware that includes brackets.   

Our blog post today falls somewhere right in the middle.  We managed to obtain a bolt over style grille for our Chevy Colorado, used for about $60.  Personally, we too enjoy the lines of a billet grille, but wanted the cleanliness of the cut out style for that real custom look.  The only think standing in our way... Brackets!  So we decided to make our own.  Easy enough right?

This post works well for leading you through the steps of installation for a cut out grill even if you have the proper mounting hardware, just eliminate some of our fabrication steps and use the hardware and instructions given to you by the manufacturer.

Things you will need:

• ½” by 1/8” aluminum flat bar ( ours was an 8 foot length)
• Drill, or drill press
• Dremel style rotary tool, or a small grinding wheel
• Tape measure!
• Pliers
• Vice
• An afternoon, and a beverage of choice
• Hacksaw blade
• Hacksaw
• Assorted hand tools (files, screw drivers, wrenches), so have your toolbox ready

We started by removing the grill assembly or grille shell from the front of the truck. Each is to there own on this one, they are all different.  For us, it was a matter of 5 clips and 2 light harnesses.

Make sure to take a second and look it up or ask someone who may know, because there is nothing more frustrating then starting a mod only to break something else.  

 

From there we took our grille to a clean workspace and started the surgery.  We cut neatly along the top of the grille with a hacksaw blade.  This seemed to work the best, providing us with a clean cut that we could later smooth with a grinding wheel and file.

 

Once the top of the grille was cut loose, we flipped the grille assembly over to expose the plastic “welds” that held the black mesh into the  grill shell.   

With the rotary tool and grinding drum attachment, quick work was made of the “welds” as they were buzzed off flat allowing the black mesh to literally just “pop” out!

The grille of the Colorado is now hollow, with the one cut edge along the top, that we wanted to smooth out a little.   

 Again using the rotary tool with the sanding drum, and a small hand file we smoothed this edge up and rid of any small bumps or plastic imperfections left behind from the cut. 

Now the tricky part!  Once we had our empty grill shell we began to lay out the brackets with our ½” aluminum flat bar.

 Please take your time with the fabrication of the brackets.  The brackets are a crucial step that will ensure your grille sits flush on the outside, stays centered in the grill shell, and these brackets will also provide rigidity to the entire grill shell once the billet grilles are mounted.

We stared by laying the grille in the shell face down and began setting up our lower brackets.  We place them across the grill to get a visual interpretation, then took the appropriate measurements and marked the length of the hardware and location of the mounting holes.  Finally we cut the bar and pre-drilled our top and bottom mounting holes as well as the bolt holes for where the grill will mount. The lower hardware is good to go. 

Our Colorado was a little tricky, and since these brackets are all original and we do not have the store bought kit, we made a custom cross brace that aloud us to tie all the brackets together and insure the grille won’t shake all over the place.  We did this because we had nothing to mount our brackets to on the bottom of the grill without it being visible.  *Remember, the cleaner the better* we took the extra time to make this install nice and clean. 

Therefore, after making the 2 vertical brackets, straight and simple with 4 pre-drilled holes, we moved on to the custom cross brace.  We drilled a ½” hole through the middle lower grille shell mount, and twisted the aluminum flat bar in the vice in order to get the brace shaped the way we needed it.  We then pre-drilled the ends of the brace, where it would meet up with the horizontal brackets we just completed as well as the upper screw hole, where it will mount to the grille shell mount.  Now we have successfully completed all of the lower hardware which definitely was the more difficult part.

The upper grille was a little easier.  We measured and cut 2 pieces of flat bar and bent the ends to about 50 or 60 degrees.  This modified “L” bracket design was then pre-drilled for the grille bolts and upper mounting screws.  The “laid back L” shape let the brackets rest nicely under the upper black plastic of the grille shell, while keeping the front of the billet grille flush in the shell.  The Last 2 brackets were by far the most simple, and involved no more than a couple straight pieces of flat bar, again pre-drilled for the grille bolts and 4 mounting screws. 

Once all our hardware was done we mounted it all up and test fit the grille and hardware, to position it right where we wanted it, before marking and pre-drilling the mounting holes in the grille shell.  After, the hardware got a quick coat of paint to black them out, and we were ready to mount the grille!

When mounting the grille we made sure to take our time to avoid scratching the grille shell, as well as our freshly painted hardware.   Mounting this two piece upper grille was done one section at a time. 

We started with the bottom section first because it is the most rigid section of the grill shell.  This is important because we can better guarantee that the grille will mount straight, and without stressing the shell.  Once this lower grill is in place, its presence in the opening and the hardware will strengthen the upper portion of the shell from flexing when installing the upper grille.  This is just our recommendation.

Back to the install,

We secured the hardware snug, but not tight, to the lower grille and were able to place it into position from the back of the shell.  We then centered it, and place two ½” screws into the shell through the upper holes in the hardware.  

All of the holes were first pre-drilled to make sure our screws didn’t crack the plastic, but instead tap through it. 

Yes! Our hardware is long, it was later cut.  Recycle:)

We then placed our lower cross brace through it’s hole in the lower shell mount, and secured it to the two pieces of hardware with two ½” screws.  This stopped the grille from moving from side to side and up and down once we mounted the brace with its ½” screw through the shell mount.  Finally we tightened down the grill bolts and moved on to the upper grille.

We started by placing the upper grill gently in place.  Then we positioned the hardware and secured it to the grille.  Next, we lined up our pre-drilled holes and placed four ½” screws through the lower mounting hardware and into the grille shell.

 

The next step was to flush the upper black plastic to the top crossbar of our upper grille, and just secure the two ½” self-tapping screws from the top, trough the black plastic and into the upper mounting hardware.

  Now turn it around and take a look.  If you’re as lucky as we were the first time, it came out beautifully and sat nicely in the grille shell.  It is not irregular for some installs to need a little tweaking though, so don’t get disappointed too quickly. Plus, there’s no saying you can’t go back and fiddle with it later, if you want to, just pop off the grill and adjust your hardware as needed.  The slotted openings in the actual grille, where the hardware mounts, provide adequate adjust ability and should allow you to center the grille perfectly or very close to it, and you are done!  Just re-install your grille shell the same way you removed it and drive on.

Yup, there's the look we had in mind.  Sleek, clean and aggressive.  Perfect! Enjoy guys.
