Replacing Master Brake Cylinder

Anyone ever replace their master brake cylinder. any estimate on how long it would take and any special tools. i was told by my local mech. that only the dealership can do it cuz you need a special tool to bleed it, but it doesn’t say anything bout it in my haynes manual.

special tool to bleed my ass. any bleeder kit will work or even some clear hose and a bottle. best thing to have though is 2 other friends, one to pump the pedal, one to watch the MC level and you to lie on your back and bleed the lines.

some flare wrenches would make life easier so you don’t strip the nuts on the hardlines. job is really straight forward.

thanx…appreciate…maybe i’ll do that this weekend.

Brake Master Cylinder Seal needed

Hello all:

Before you off to get the Master Brake Cylinder part, there is also an oil seal that need to be replace as well. OEM Cost like $3.50 or so. I got my MBC from Central Auto part for $29.00 with lifetime warrant on it.
HTH, This info based on 92 GSR
Good luck

im going to be replacing mine soon also. i have heard that its not hard, hopefully its true.

It takes about an hour to do. Make sure you have a flare nut wrench (10mm and 12mm).

good looking…
