$141 for master cylinder & brake bleed

[anatomiczero]

My brakes just went out this morning going to school, they stop but only with the pedal all the way to the floor. So I called Less Scwab and they want $141. I need to know if it's difficult to do it myself. Does the MC just bolt on to the brake booster or is there some kind of linkage. If I bench bleed it should I beable to take it to Les Schwab just for the power brake bleed?

I haven't redone my master cylinder yet so I can't help you out there, but I can tell you that bleeding a brake system is easy. Just go to the autoparts store and get a 1 man bleeder kit and brake fluid. It is easiest with 2 people, but can be done alone.

if ya bench bleed the master you should not have to bleed the system at all.
a reman. MC will cost under $20 and take all of 5 mins to install.

Save $100 or more do it you self. Not hard at all.

$20 bucks for a reman master cylinder and about 2 hours of your time, get brake fluid,and a set of wrenches and you can do it , once you have the new master cylinder put it in a vise, Don't make the vise to tight you can warp the piston bore, it "should" come with two plastic plugs screw them into where the lines go on the new unit pour some brake fluid in the resivoir(sp) use a wooden dowel rod
,extension,small hammer handle and move the piston in short strokes about 1 inch until no more air bubbles come out, fill it as it is needed, It will take about 15-20 min,

the master cylinder is held on with 2 studs attached to the vaccum booster,loosen up the brake lines first to do take them off yet just make them finger tight, take off the 2 nuts and then the lines, Where the mater cylinder goes in to the booster there might besome rust,dirt,ect clean it out with some brake cleaner and wipe it out and put the mater cylinder back on the way it came off.

I would make sure it is the master cylinder first it "could" be a wheel cylinder

Could be off my rocker here, but I don't believe you have to bench bleed the master cylinder.

Last master cylinder I put in, instructions didn't say anything about bench bleeding, and I didn't, and it works fine. Didn't bleed the lines either, since I had already done that and knew there was no air in the lines. As I understand it, if the master cylinder has air in it, the air will rise, and thats fine.

Yes, you need to bench bleed the master cyclinder. This is because the normal stroke of the piston inside the MC is less than the actual stroke available - air will stay trapped there forever unless you bench bleed it and depress the plunger fully about 15-20 times until no air comes out.

When you clamp the MC in a vice, do NOT clamp the body itself. Clamp an ear of the mounting flange. That way you cannot warp the piston bore (bad juju.)

I recommend you buy an Autozone remanufactured MC for about $20 plus core charge. It will come with instructions and also will come with the plastic deals for bench bleeding. All you need in addition to that is a vice and a phillip head screwdriver to depress the plunger!
