Car veers left when under medium to heavy braking???

[mikeetown]

To start, I replace the front brakes including the caliper. So, they work Great. (car has ABS) It still is veering left just not as hard but still extremely noticeable. I will be cleaning the rear brakes on saturday. I am going to re grease the sliders and check for a faulty caliper. However, I don't think anything is wrong back there but I have been wrong before haha. I removed my tires and reefed on everything under there and it all is solid. I even took a wrench to every bolt I could see. I also checked to see if my Ball joints an tie rods are good and they are. My tires are 80% tred life 195/60/R15 winters. The car is lowered 1" but has had its allignment. Tire pressure is 32 PSI.

If my MX-3 GS still is veering left under a medium to heavy load on the brakes, what could the problem be?? It only started after I did a winter x-cross on a small course that was .4 miles long. The course was not an issue i believe to the car or very rough because I couldn't red line second gear at all (if you know what I mean, it was twisty).

could it be a control arm bushing??
I'm PISSED !!! HAHAHAHAHA

Check your rear calipers too. I have a faulty RR one on the summer car (recent occurrence) and it makes the car pull pretty hard to one side.

Could be tie rod end, ball joint, control arm bushings... anything that takes the braking load. But it seems you checked that out.

Racing is hard on suspension. You could check your alignment again. You can check your toe with a measuring tape at home first though, I'd think you have one tire that is toe'd in a fraction of a degree more than the other, just from hard corners. It happens. Potholes will kill your alignment too.

I'd say yes, something is causing the driver's side wheel to go out of alignment when you apply the brakes. The load on the wheels is much higher under braking with a 2400lb car pusing on it than you can probably produce with a wrench or a pry bar. I've run into this myself where I had a bad clunk in the front end and no matter how many times I inspected it and pushed and pryed on stuff I could not find it. turned out to be the control arm bushings.

yea ur FR caliper is getting stuck so when ur brake it turns left so all the braking is only done on one side which is pulling ur car left and the right caliper is not applying pressure so its not braking . possible it is not ur rear calipers cause they are not as used as much as ur front . so check for small leaks on the right side of caliper , the seal and hose cuz pressure is lost or leaking or just a stuck piston on the caliper .

So, I finally got the time to check everything over. Now, my car brakes very nicely with my crappy midas rotors and pads. I guess the reason it veers left is cause of something I can't check when the car isn't under driving loads. So, its probably a control arm bushing because the car still veers lefts after an:
-alignment
-new front calipers
-checked back calipers cleaned and greased
-good suspension
-tie rods, ball joints, sway links all great

DAMN!! haha.

Try laying under the rear end and getting a friend to play with the ebrake.

If the little arms on the calipers do not return, then you still have a seized caliper issue.

Try turning the rear caliper pistons in. This should be difficult but possible. If they don't turn, seized, if it doesn't screw in, messed up piston/ratchet system with the little ebrake arm.

Ya i did that with the rear calipers. They work fine. They don't look that old either. The ratchet systems fine too. The car doesn't veer left nearly as much after i greased everything on the brakes. Also, the car on veers for a second so, after something takes braking load somewhere, the car can brake straight a couple seconds after
