quick question about brakes

[bastianshaw]

what forces the calipers back open after braking?

[jlevie]

Nothing forces the calipers open, but the release of pressure and motion of the rotor allows the calipers to relax enough so that the pads aren't producing braking force.

i too have a quick question, i noticed that when im braking that the rear is also braking too and i didnt no that e30's brak on all 4's instead of in the front.

so my question is how do i remove the rear braking n just have the braking power go to the fronts???

The calipers/pistons do not really "move" in the way that you are imagining. They sit almost against the face of the rotor applying no pressure until you hit the pedal. Then they apply pressure. If they were really moving that much you would have to press the brake pedal pretty far before anything happened.

What the hell are you talking about and why on earth would you want to do that?

All cars brake with all four wheels. Every car worth a damn made in the past half century (more than that) has had 4-wheel brakes. Do not remove the rear brakes. They help stop the car.

ok...maybe a dumb question here..WTF would you want to do that? maybe remove the calipers all together? now no rear brakes and see how the car works? lol

Disconect the brake lines at the master and plug the holes.

Im chalking this up to darwinism.

(facepalm) well fuck, i was thinkg more or setting my car up for drift and have slide in a freinds e36 and in mide turn he would be on the brakes but applying gas to keep going through the turn.

i was thinking some kind of same idea for the e30's tho...lol didnt know it would be that negative. N i dont mean removing the whole rear calipers= dumb

IE sells a biasing valve look into that?

Put down the crack pipe.

Just take the brake pads out of the rear and you will get the sam effect. It will also be cool to do big burnouts.

I just ask if you use my way that you post some pics of the biggest burnout you can do.

what forces the calipers back open after braking?

Nothing, they are "forced" to the rotor surface via pedal modulation. Static pressure from the caliper piston seal and dynamic suspension flex does the job.

Actually, the square cut seal around the piston allows the piston to retract after braking pressure is released. It is also responsible for continually adjusting the distance the piston/brake pads are to the rotors.
