Brake Master Cylinder Change

[Monty_CZ]

Hi, I have a problem probably with main brake master cylinder (I did not found visible leaks or hissing) on my robin hood 2b (no servo). Brake pedal is soft and after few presses it gets firm but if I keep pressing it goes slowly down to floor. I've found out that my brake master cylinder is type TRW PMH224. But it's quite difficult to buy it here so I am curious if this master cylinder can be changed for another one form Sierra without abs - for examle for ATE 010463 or simmilar. Thank you very much for replies. :-)

As long as you can find one of the same bore and fixings it will suit your system.

The main thing is room to fit it.

If you get that right your ok.

A bigger bore will move more fluid but put up the required effort.

Obviously a smaller bore does the opposite.

I recently found out that when bleeding the rear brakes, it is much better if you lift the rear of the car as high as you can. Safety in mind of course.

Hi, on another forum they gave the equivalents as:

 

GIRLING 4006224

FORD 6186005

FORD 88BB2140BA

BOSCH 0986480608

BENDIX 132805B

DELPHI LM39027

TRW PMH224

 

You will obviously need to confirm them yourself!

Thanks! I've also found these product numbers, but it's the same product. No shop has it available here because what I have found, it's for right hand drive cars. I didn't want to order it from e-bay because it takes too long and you know... Winter is coming! So I've ordered normal brake master cylinder in local shop for ford sierra w/o abs with same bore. If there will be some problem they said I can return it. I hope that it will work.

Probably find that the pipes connect on the other side.

Should be no problem to extend the pipes round the new master cylinder.

Or even right across the bulkhead.
