Title: Brake and clutch master cylinder renewal
Post by: slow6660 on April 12, 2026, 05:50:34 PM
So as part of me continuing to try and unravel the plumbing spaghetti, I bolted up the brake and clutch master cylinders to help identify connections and this has sort of helped but I'm still after any advice as it's still quite a mess.  I think I really need to visit someone's garage and eyeball each pipe run and get better photos.

But on the real thread topic, I fitted up the pedals and so was able to try and actuate the clutch master.  As expected, it was stuck and I'm guessing the brake master is no different.  After about four decades this was no surprise.

Clagged masters.

However, is it worth me trying to get these masters professionally renewed and working again or am I better buying new replacement items?

I guess it is worth asking locally first, so can anyone recommend a Melbourne based repairer capable dealing with these two master cylinders?

Cheers
