Thread: Procedure for replacing brake master cylinder?

Silly question I suppose, but you have tried putting fluid in it and see if it pumps up haven't you ! if the fluid just pumps out you have a fault further down the brake system which needs addressing first.

Its not a fun job.
Access to the pedal boxes is hard.

I always take the pedal box out. If the old master cylinder is siezed, you need to cut the pushrod first, as the pedal has to be in the down position in order to get the pedal box out. I normally use a rat tale file to cut the pushrod, as access is quite limited.

Aaron IIA is correct - believe it or not the easiest way is to remove the pedal box (from inside the car).

Remove the springs from the pedal (if any), undo the bolts from inside, lift it out using a 90o turn, and away you go!

I learnt this trick from this forum when I had to do mine.

There is also an excellent article in November 2011 Land Rover World.

Yeah it was full of fluid when I pulled it apart.

Thanks for that. I assume the master cylinder is not seized, as the pedal goes straight to the floor.

Thanks for the tips. I'll order that magazine, it seems cheap enough. I hadn't heard of it before.

It would be better to order the factory workshop manual.

Where can I get one of those from?

I've also ordered a Haynes manual but with other vehicles I've found they aren't detailed enough.
