i'm gettin alot of right front lock up. is this because i need to bleed my brakes (i know i do anyway) or is this a bad caliper??? figures, right before my hpde, things go down the toilet.

same problem on my car, before and after new pads, rotors, remanned calipers, slider pins, and lots of bleeding.

 

gonna bleed them and pray that does it. i'll let ya know if it worx when i get back from limerock.

when u going up there....and coming back?
I'd love to go watch

 

My car will ALWAYS lock the left front a little before the right front. No matter how many new parts are in there, how fresh the bleed is or how different the alignment or shock settings are, I've come to the realization that THAT'S just how it's going to be. FWIW, you may want to look into all of those areas to see if anythings deficient. Any of those can cause your braking issues.

Oh yeah...forgot about tire pressures, too.

 

Carroll smith advises that most brake lockup issues are suspension related. take that for what its worth. (btw, he's worth a lot in racing)

 

MAster cylinder? ABS flaking out? Or what Tyson said.

Friend on mine with an SE-R had serious problems with premature lockup on his car. Traced it to ABS system.

Matt-doesn't like ABS all that much....

P.S. Try a flush and lube the pins. See what that does for you. Worth a shot and that's a cheap/easy first step to take before you start spending real money on remanned calipers/master cylinders...

yea, i think lubin the pins amy help as well. what should i lube them with? anything special?
suspension is stock, till next week. so i can't do anything about that. although my car seems to lean to the left which would make the right side lighter. hhmmmm. i'm gonna bleed the anyway because i don't know the condition of the fluid and a full season of autocross hasn't improved the fluid any.
i will also check the pressures but i believe there within 2 lbs of eachother.

edit-i don't have abs

Another cheap thing to try before investing in new parts would be to get some brake spray and give all your friction surfaces a good cleaning. A greasy handprint on a rotor can really have an effect.

 

I picked up some caliper pin lube at the auto parts store (Autozone, IIRC). Sitting right next to the counter. Cheap and lasted me ~ 1 year.

Along the suspension theory, could one of your shocks be blown???

 

dam i should have addressed this earlier

 

I used high-temp valvoline synthetic grease. It's probably overkill, but you can use the stuff for tons of other things on your car and it'll stand up to high temperatures. I just took the pins completely out, cleaned with a clean rag, dipped them in the grease, cleaned off the excess and put them back in the calipers. Make sure the pin boots seal completely and ripples in the boot aren't twisted.

a silicone lube. very similiar to lube for polyurethane bushings.

This is probably the silicone lube Im talking about.

so i just got in from lrp. good event. the brakes felt good with the hp+. no lock up problems. i'm still gonna grease the sliding pins on the calipers one of these days and re'bleed the system. thanks to carbotech for the help as well as everyone else ont he board for there input.
