Post subject:  Brake Master Cylinder Repairs

Does anyone know about a brake booster with the master cylinder bolted from the inside of the brake booster. Without hacking at it I don't see how they come apart, if at all. Want to replace/rekit the master cylinder as everything else has been done on the brakes (see picks in my link)

The brakes are not holding pressure even after several hours of bleeding. Before converting the brakes over, they failed on me, which I thought was wheel cylinders as they were leaking, but could be related to the master cylinder

hey dan, did you change the rear wheel cylinders?? my mini had the same problem and after i changed them it was fixed. They dont need to leak fluid to let air in either, so hard to know when one is leaking.

G'day Brad,

Yeah I replaced both wheel cylinders and I put rekitted camira disks and calipers on the front.

I am getting fluid through the lines. I can pump up some pressure when bleeding, but it just falls away when released again.

We did this for two hours and it would not retain pedal pressure.

hey - check the bleeders on your calipers, make sure they're at the TOP of the calipers, if they're at the bottom, it makes them nice and easy to bleed, but you also get a nice big air bubble in the top of them that will never bleed out - I learnt this one from weeks of bleeding and head scratching, I had them on the wrong side
