Original rotors and second set of pads with 35k on the odometer, my last track session finally resulted in needing a complete front brake job. This thread is specific to the rotors, but in step one I have a link to pad only replacement.
Most everything you need for this project:
1. New Rotors/pads (Raybestos rotors ordered from RockAuto.com
and the pads are OEM)
2. Brake Cleaner
3. WD-40 or equivalent to spray the hub
4. Disc brake lube for back of the shims
5. C-clamp or flat head screw driver to push the pistons back in the caliper
6. Hammer and Pin-punch to tap out the top pins
7. 13 and 17 mm sockets
8. M8x1.25 bolt to help remove the rotor
9. Torque bar
10. Towels and Gloves
Remove old brake pads as described in this thread
After removing the pads you can then remove the (2) 17mm bolts that hold the caliper in place. This is what you should then have. (2) pins, (1) center bolt, (1) anti-rattle clip, (2) 17 mm bolts and (2) very worn pads. (notice the hair line cracks!
I definitely won't be using stock pads at the track again.
When you remove the caliper place it on something such as a bucket to prevent damage.
If you have a micrometer you can check the thickness of the rotors. They call for replacement at 28mm in the front. I measured 28.75, which is close enough for me.
Spray some WD-40 or equivalent around the center hub. After about a minute take that M8x1.25 bolt and tighten into the rotor until the rotor (pops) free. My rotor was loose enough that just the one bolt was enough.
Remove old rotor and then remove any rust/debris around the the hub area to ensure the new rotor is able to sit flush.
Install new rotor ensuring that it is fully seated against the hub. Once positioned I used a lug nut to temporarily hold the rotor in place. <<<<<< Just don't over tighten. With the rotor in place you can remount the caliper and torque to spec.
Install the new pads as shown in this thread
Double check that you tightened everything down and put your wheel back on ensuring you torque to spec.
- Double check everything including your brake fluid reservoir cap!
- Put your wheel back on and torque the lug bolts to spec
- Embed the pads to the rotor properly. I do several 60 to 10mph slow downs. Do not come to a complete stop!
- Clean up and savor the money you just saved by doing this easy brake job yourself.
