How-to, 4Pot Brembo BBK on cheapish...
Intro
The EVO8/9 brakes are almost direct bolt-on on our cars. They fit very well but not perfect. There is about 5-7mm of wasted pad surface. It could be fixed with a larger rotor but over all they will function 100%. A few Mazdaspeed6 guys have been running them for some time with great results. Depending on the deals you get, you can do this upgrade for $500-$700 bucks. Not bad considering 4pot kits normally run between $2k-$3k!!!
1. Shopping list:
Required:
EVO8/9 calipers, Make sure they come with hardware and caliper bolts. A used option is best.
Caution with cheap new calipers or cheap rebuilds they may be FAKES!
EVO8/9 Brake pads
Evo8/9 Rotors, OEM Evo rotors DO NOT fit. Buy Centric or Stoptech Rotors. They are a direct fit.
2mm wheel spacer or equivalent, will go more into detain in instructions.
-I bought 3mm hub-centric spacer, took them to the machine shop and had the id/od matched with the rotor and thinned down to 1.90mm. That is a perfect spec. According to my measurements 3mm will end up rubbing on the outside of the caliper.
2Qts of Brake-fluid Dot3/4
Large enough wheels to clear the calipers. I have Enkei GTC01 17X8.5 +35
Recommend:
Front and Rear SS brake hoses, Use hoses made for the protege they work will with the Brembos.
Caliper paint - Black for sleeper status
New decals
2. Prepare:
Clean, paint, and install new decals.
Once you are done you can stare at their magnificence
3. Get to work:
Make sure you have a lot of time to do the job before you begin
If upgrading Brake lines, spray where they attach with some penetrating oil. Let them soak while you work.
Remove your old calipers and rotors. Wait to remove caliper from brake line until you test the wheel clearance.
Now that everything is out of the way you will need to file off about .5mm of material from the lower caliper hole on the knuckle.
Test fit your caliper, Stare at the awesomeness.
Remove Caliper
Place 2mm Spacer BEHIND (before installing) the rotor. The rotor needs to be pushed out so it lines up correctly inside the caliper.If no spacer is used the rotor will drag on the caliper.
Install rotor. Place wheel nuts to hold the rotor back, this will make installing the caliper easier.
Install caliper. Check wheel clearance. Torque caliper bolts to 80 ft-lb +-7ft-lb. Do not over tighten or risk damaging the caliper.
Install brake pads. Nothing fancy. Install one pin, then place the hold down clip, install second pin. Takes like two minutes.
Install SS Brake Hose
Repeat all the steps on the other side
Install Rear SS brake hoses
You will need to bleed the entire brake system:
1. Rear Right
2. Rear Left
3. Front Right Outer
4. Front Right Inner
5. Front Left Outer
6. Front Left Inner
Repeat as needed.
Install wheels, torque lug nuts to 72ft-lbs
And you're done! Enjoy your Bad Ass Brembos!
