MG Midget and Sprite Technical - MG Midget 1500 - 1979 Master Cylinder

Hi Guy's,

The brake pedal was solid and would not depress properly - noticed that the the back brakes were not working efficiently so decoded to replace rubber hose and pipes all the way back. The brake will depress now (prior to bleeding the system) but the brake pedal won't return to it's starting position, put a new spring on the pedal, still no joy.

I have decided that it is probably the master cylinder, but trying to remove it to replace is a nightmare, I can get a socket on bottom nut of the cylinder, but can't get a spanner in to the top nut to remove it - short of cutting a hole in the side of the pedal box I'm stuck ! any advice/ tips on how you did or do it / or any help appreciated I was also wondering if I could replace the rubbers e.t.c. without actually taking off the master cylinder ? .....

Many thanks for any help

I remember it was awkward, but do-able.

I wouldn't even think of trying to rebuild it in-situ.

Search the archives, there are various descriptions of disassembly to be found there.

I had to remove the bolts and screws holding the pedal box to the body and then lift the master cylinder to get to the bottom nut. Break the brake lines at the master cylinder first.

There HAS to be an easier way, but that's whet I did a couple of months ago. A pain, but doable.
