Where these pads new? I always thought you had to gently break in pads, such as multiple 30mph near stops, avoid getting them hot for a while to "bed them in".


No, they're not new. About 5 yrs old, with about 8000 miles on them. I took it easy on them for a while when they were new.

Maybe its not the brakes. Maybe repeated braking caused the tires to heat up and become more sticky?

Good point

That's not what's happening. If the tires had started out cold and slippery, then the first hard braking test would have resulted in locked wheels. I could tell that the amount of force needed on the brake pedal was getting lower. On the last 2 "tests', I had to modulate the brakes to keep them from locking. I.e. I had to apply less than full force to the brake pedal. The brakes were definitely developing better braking.

Maybe the rust from the calipers got on the pads and it took a few more stops to get it rubbed and shaken off the pads

I finally have an answer to this. I got the chance to take it out again today, 8 days after the last drive, and the brakes were great from the beginning. No heating required. So this means that it was a one time thing... Something like moisture in the pads, or glazed rotors. Either way, my brakes are GREAT now! In fact, I wish that it took a little MORE pedal force to get to lockup. They're just slightly more sensitive than what I'd consider perfect. I'm convinced that if everyone's stock brakes worked as well as mine, there wouldn't be a market for brake upgrades, unless it was for larger rotors to go with larger wheels.

Edit: After thinking about this, I retract some of that. I can see upgrading solid rotors to vented to improve fading.

You do have a Formula with vented rotors.....no?

I have one....and I agree, the brakes are excellent.

Yes, a Formula with vented rotors. My comment on upgrading solid rotors was for pre-88's.

Are vented rotors available for the pre 88's?

People have come up with ways to install vented rotors on pre-88's. I don't know the details, as I don't have a pre-88.
