Master Cylinder Seals

Recommended Posts

sherly

Just fitted new front discs and pads and have decided I want to change my brake fluid too as it's a bit of an unknown but I've noticed some fluid leaking around the master cyl.

I'm guessing this has happened because the seals were borderline and as I forced the pistons back without opening the bleed nipple on each caliper to expell the fluid it been forced out of the seals.

 

Is it possible to buy these seals seperately? Master cylinders don't seem to be very expensive (£30 ish) so is it better to just put a new one on?

 

Cheers,

Mart :P

The seals should be available seperately, part numbers here.

 

That MC doesn't look very old, its still slightly bronze coloured so just the seals should be enough imo.

I just trawled back through the service history and it had a new master cylinder in '99 @ 92k miles. The car has now done 172k.

 

Looks like I could have another 10k miles left in it then.

 

If I decide to just change the seals does the fluid reservoir just pull out?

are you sure it is not just excess fluid pushed out the reservoir when you fitted the new pads and pushed back the pistons?

Yup - definately not. Made sure there was enough room in the reservoir before I started (for once :ph34r: )
