Default Anyone rebuilt a master cylinder?

My master cylinder is leaking at the base. I know that I can buy a rebuilt cylinder but it would probable be cheaper to rebuild it. The brakes have been spongy for a while and the leak is getting worse. Even though I am licensed I have never rebuilt a master cylinder (it is cheaper and better for the customer to go professionally rebuilt). So what I am asking is if anyone else has done it and can share anything?

I guess this is one of those "whatever makes you feel good" type of answer. But I would buy a rebuilt unit and then bleed the entire system really well. Also, at this time I would look at all of your rubber brake lines. If you have the originals on yours I would replace them too.

I am thinking that way....only because the whole job takes under 2 hours, and being from Canada and the car being 12 years old....the flex hoses have been replaced twice already Thanks for you thoughts.

Well funny you should post this question...My master cylinder is leaking also..BUT I could not find any supplier for the re-build kit..Where did you find one..I have found a new master at AZ for $55.00...not too bad of a price, considering that re-building existing one would take longer, time wise...

I would say buy the rebuilt one -- the rebuilt kit (if you find one) is probably going to be a little bit less but you'll have to spend time rebuilding the old one. For your time, I would say just get a new one.

Over 20 years ago I remember being told that at least in some states ,that master cylinder rebuild kits were not available to the man off the steet.A repair shop probably.Seems to have been related to accidents caused by DIY/backyard rebuild jobs.Can't remember which car it was for.Must be my arteries hardening.
