Hi,

Had my Clutch Master Cylinder replaced (original started dripping down pedal). New part is super, but have noticed push rod is longer than original which gives a long/high pedal.

Does anyone know if the old one will last if I repair it or how to tell if the bore is too worn? (also if it is worn, can you get them rebored?)

Also original one was a girling one which had a plastic tag around it, what does this mean? The tag is brown plastic and has a number stamped in it like old fashioned dymo (they don't seem to relate to a date). Is this an original thing or a sign it has already been rebuilt?

Clutch and brake master cylinders can be rebored at Apple Hydraulics with either a bronze or stainless sleeve used.

Same thing happened to me. Just take the old rod out and put in the new master. Pedal will be were it was before

I've rebuilt and replaced a number of the clutch master cylinders over my 28 year ownership.

It's really easy to rebuild one of these with the overhaul kit and a lot cheaper. I've found that it's the rubber seal that eventually degrades at the top edge. That's probably where it's most susceptible to water and air ingression and eventually deteriorates. The bore wasn't corroded at all. So long as the new seal is treated carefully during the rebuild it should last several years minimum. The kits usually supply some red type grease that's needed for first fitment. http://www.rimmerbros.co.uk/Item--i-GRK1029

IIRC the circlip is a bit fiddly to remove and replace but apart from that if you can replace one master cylinder for another then it's a n easy job.

Hope this helps

Thanks everyone.

Solved easily by swapping push rod. Old cylinder sorted by rebuild.
