my track car (92 Si, cage, full suspension, etc.) arrived today, and during my test drives I'm having a real hard time with the brakes. the car just doesn't want to stop!

it has 11 inch prelude rotors and calipers on the front(no idea what year Prelude though...), stock Si disks & calipers on the back. It has HP+ pads, and motul fluid, but rather old (several years old). I am flushing fluid on friday before my track day on Sunday. Oh, it has the 1" Master cylinder too.

The brakes are extremely non-linear. Almost like they are glazed or something. mild pedal pressure slows the car down, but after that it takes almost extreme pedal pressure to get any further braking. It's very difficult to get to the threshold (and this is on rock hard old school Azenis). Not sure how I'll do when I put the r-compounds on...

I did about 6 85-30mph hard brakes to see if they were maybe just too cold, and that helped a little, but not much. It's like the breaking plateaus early and it's really hard to get anything beyond what it initially offers.

Any advice? I can buy new brake pads, but I don't know what size. What year prelude are the calipers that fit on our cars? 92 as well?

Thanks so much!

P.S.: now that I have this thing, someone buy my Evo IX!!!

 

if it had race pads id say SOP, but the HP+ are a street pad.

maybe the booster is bad. Take the vacuum line off of the boost and see if it feels the same way.


Also make sure you aren't pressing on the gas too when you are getting on the brakes, with this being a new car it might be happening. I had a 'pro' driver over shoot the pit box and almost take some of us on the crew out, plus he got us a 2 minute penelty

That is def happening too. The pedals are for heel-toeing, and it's almost difficult to not press the gas when braking.

good thought, I'll spend some time on practicing that. (sounds really stupid, I know, but gas and brake are very close, and it's the first time I've had real pedals.
