Brake master cylinder

[Snaek]

Hi,

I have the pedal box out of the the car (4.0 1995) and want to replace the seals in the brake master. Does any one have numbers or any ID for the seal kit or the master cylinder itself.

Speak to Brakes International, they do a whole master cylinder (ford xr2) for around £80. Not worth replacing the seals when the unit is so cheap.

You can get the master cylinder out from above as well, just have to pull out the reservoir, then you can access the bolts

I would never replace seals on brakes...life is too precious.

Thanks for you comments, looks like a new cylinder then.

why not - does the metal wear out?
surely it is the rubber seals that perish???

The cylinder is steel and I very good condition without any leaks. I just thought it would be prudent to change the seals as I have the pedal box out.

CLEAN & PRECISE.....is to work without any mistake/scracht on surface !
But if you never maded it before.......ask a specialist/mechanic for
assistant/help.

The OP has clarified his position in choosing to replace the seals whilst the cylinder is on the bench which does make sense.

If a cylinder is leaking then in my experience not only will the seals be worn or perished the cylinder itself will also be worn or corroded. The corrosion is not just because water has gotten in it also comes from the dissimilar metals used for the cylinder and piston.
The wear come from the metal piston not just the rubber seals.

Is it worth the risk when your life is at stake?
