So i have a spongy brake pedal, while driving the first pump on the brakes doesnt stop the car but the second one does.
What ive done so far, checked all calipers, replaced FR cause it was leaking. Reaplced master cylinder and bench bleed it, bleed it about 15-20times, we did it at a level ground, the back up in the air, and with the car being on. there is NO air in the system, And once in a while my ABS comes on when WOT or just reg driving. Also when my cars idleing around 700 rpm if i pump the brake pedal my rpm drops to about 500 and sounds like its misfireing. all the vacum lines are new and correct. could it be the Brake booster check valve?

Yabba Dabba DOO!

How many post have you done in the past weeks.
Everyday is a new question. You can't remove body trim without asking why are you even look at brakes?
I really want to help you but take it to a licensed mechanic because you are going to lose your brakes and either kill somebody or yourself.

Sorry my soul is kicking me for this post but I can't take this anymore!!!!!

You don't bleed brakes with the car on...
Don't jack up the rear...
Probably have a pin hole in a brake hose...
Your vacuum is not right...

LOL......Idk if I should laugh or cry..

No, I just dont know that much about mechanics. Today under hard braking i noticed the steering was being pulled to the right. That means my left calipers is bad?

Im going to stop being a cheap ass and im just going to replace all calipers with brand new ones.

you dont need to when what you described sounds like the left front caliper is seized like you said yourself. toyzforme is either high or just read that wrong. when i first got my supra, when we did the safety, my right front caliper appeared seized, i ordered one then my buddy popped the line off and no fluid came out, i guess he hit the pedal and a chunk of something came out and all was well. i was away ordering the caliper so i missed all of this. hes not full of shit though after that the caliper worked. ive never seen that before. shot in the dark but pop the line off and see if you have fluid flow through that flex line. again, random but hey, ive never seen that shit before and it happened to my car. also push in the caliper with the line off to clear whats in the caliper as well(because again, i wasnt there and it was a year ago, it may have been shit in the caliper not the line)


if your going to keep fucking around and driving with no brakes though, take it to a god damn mechanic man. if you cant afford to have it fixed properly, you dont deserve the car. first of all other peoples safety is at risk and its a supra, quit being cheap.


ninja edit: you may even save money taking it in. you'll defently save time...

i hate to thread jack, but is air bubbles is the resoivior normal?

I have to disagree to a particular part of this.

I don't believe because you can't afford something means you don't deserve it, I think the fact he is neglecting to fix the issue before driving it says he doesn't deserve this car, or any other vehicle for that matter. so I agree to disagree I guess...

7mgte: if you don't know what your doing, take it to a mechanic or find a friend who DOES know what he's doing and at the very least have him supervise what you are doing. brakes isn't something to tinker with when you have little to no knowledge, especially on a daily driver. so please find a few IQ points and call a knowledgeable friend or take it to a mechanic before you kill yourself or someone else.
