This page descibes the process which i used to
refinish/repaint my black s4 brake caliper to red. The task is
VERY easy , very cheap to perform and looks like a million bucks
Basic items you will need.
- Gloves to keep the hands somewhat clean especially when
applying ZIP STRIP
- Saftey glasses
- Mask to eliminate breathing brake dust
- C Clamp
- Wire brush
- Drill with a wire wheel
- Wet n dry sand paper
- Masking and duct tape
- Some carboard boxes to place the calipers in as you zip
- ZIP STRIP paint remover and a brush to apply it
- Caliper paint of your choice of color/brand...and some
clear coat. I used engine paint "clear coat"
- Brake cleaner.
- Wooden dowl rod..i think i used 3/8" to plug the
hole where the brake line came out of the calipers
The steps are very basic
- jack and support the car... i did all 4 calipers at the
- remove the wheels
- remove the calipers and brake lines...as well as the pads
, the sensors and also the springloaded clips that retain
- Using a wooden dowel, plug the hole where the brake line
entered the caliper. This prevents dirt entering.
- Clean as much as possible the crud from the calipers with
brake cleaner and the wire brush
- Using a C clamp i pressed the pistons back into the
calipers as i didnt want paint on the side of the
pistons..you may have to remove the bleeder screws to let
- With a brush, apply a liberal amount of ZIP STRIP to the
calipers. Just cake it on. In a few minutes the old clear
coat will bubble and seperate from the surface of the
caliper. WEAR GLOVES AND GLASSES..this stuff burns when
on your skin!
- I then took my calipers to a high pressure car wash and
hosed them off. The old clear coat came off
effortlessley. In the spots it didnt i just applied more
ZIP STRIP and repeated the process.
- Once dry, i scrubbed the calipers with a wire brush and
the wire wheel on my drill to prep the surface...i also
took the wire wheel to the retaining springs to clean
- I masked off the bolts and the metal lines with masking
tape. This is optional but gives you more of a
professional look when done.
- I inspected the surface and made sure it was clear of
dirt, lint and brake fluid
- I sprayed appx 4-5 coats of caliper paint to the brakes,
each coat was fairly thin. The brakes are black so it
will take several coats to get a nice RED finish.
- I allowed each coat to thoroughly dry before applying the
- Once i was satisfied with the finish i applied a light
layer of engine enamel clear coat and allowed it to
- I masked off the area around the PORSCHE lettering with 2
layers of duct tape and then sanded the raised lettering
with some wet and dry sandpaper on my vibrating
sander...this exposed the bare aluminum finish for the
- Remove the masking tape and your done!!!
Below are some pictures of the process.....not particularly in
the rear brakes require a 19mm wrench
on 2 bolts to remove the caliper

squeezing the retaining spring for the front pads
retaining spring removed to access pads
the front calipers are held on by 2
rather large allen bolts. You may need a cheater to aid in
loosening the bolts.
flat blade screw driver to gentley pry the pads back and off the
bolts are out, brake line removed and the pads are pushed back
the caliper comes right off!

sensor and clip removed.
removed...and cleaned with brake cleaner
squeezing the pistons into the calipers to keep paint off the
sides of the pistions.....you may have to open the bleeder valves
to let fluid out
caliper covered in ZIP STRIP..clear coat is bubbling off.
clear coat removed after a HIGH PRESSURE WASH...note the wooden
dowel rods in the brake line holes to keep dirt and water out.( a
good tip from a fellow Rennlister...thanks)
calipers prepped and ready to paint...lines and bolts masked off
and the caliper suspended via wire.....and a Corona in the corner
after the paint was applied and FULLY CURED.....using a vibrating
sander to expose the aluminum finish of the calipers to show off
the PORSCHE lettering. I used 2 layers of duct tape to protect
the area around the letters as i sanded....i used some 400
the results below speak for themselves!!
the products i used to achive the results above!!! Its ALL in the
PREP. that gets the good results
All in all, this was a very easy project and as you can see
visually worth while! A nice set of wheels will show of the
