its a big job to do , i thought it would be better to change both as i don`t want to go through all this again .the master cylinder cost me just over £50 new from flea bay , it would cost alot more to do the job again in a year or two

sorry Daz,is this the servo leak thats the cause of your lean running problem(white plugs)? or it to early to say,be an added bonus though if its leaking it will only go good with the new-un.

A whole new cylinder! Luxury not that you'll need to do it again but you can get a re-furb kit for the master cylinder for about £12.50 which replaces the components that would fail.

Cheers,

That would be seals then? But that's no good if the bore is worn/damaged.

True, but I have to admit the only damage I have seen to one (and fixed) or indeed heard of commonly is the seals getting "ripped" due to lack of use - exactly how you mess up the bore on a master cylinder I have no idea

It's very easy to do that when bleeding the brakes, because the brake m/c tends to stay with a small range of travel normally which can cause a step at the bottom of the travel. Then when you push the pedal to the floor during bleeding you rip the seal.

..that isn't going to damage the bore though is it Pete..? I'm just musing on how you mess up a master cylinder to the extent that you can't re-furb it.

Internal corrosion,its only mild steel after all,thats why i like the ALLOY stuff much more likely to reseal,dont think i would re-seal a brake master though new ones cheap enough.
