Hey Guys,

Thinking about rebuilding my master cylinder with available kit.
Anybody done this and had good results?
How hard is it rebulid?

Thanks

Lets see.

Clutch?
Brake?
Vehicle make?
Vehicle model?
Bore good or scratched?
Vehicle age?
Vehicle condition?
Your mechanical abilities?
Do you have a kit or are you looking for a kit?
What is included in the kit?

Answers to the above questions would greatly enhance the chances of you getting a useful reply.

Ok,

89 Pajero (inport)

Brake

Bore condition unknown as still on car

Good ability - just never done or heard of this kit so asking to see if rebuilds are effective in this application.

Was ringing around for replacement and they said they also have kits.

Dont know what's in kit.... Assume all relevant parts for rebuild?

Thanks

Price a new PBR or other name brand one first. Obviously will cost a bit more but undo the pipes, a couple of bolts and put the new one on straight away. Do up the bolts, connect pipes and bleed. Much quicker. Big time saver if not much more expensive. And new quality, not however it turned out quality.

If there is too much wear on the cylinder itself, you should consider a brake specialist, i don't think it costs too much for a rebuilt master cylinder. Give South coast brake resleeving a bell for a price first, on the gold coast. From memory a master cylinder was about $200 to $300, (dont quote me, it was awhile ago and it was for a NA pajero)

If you're ringing around for prices try these guys. They can sell you a kit, a new one or recondition your own unit/exchange.

you will probably be surprised at the lack of price difference between a kit and a replacement master cylinder complete. if your time is worth anything at all then a new replacement is probably the best option. brake master cylinders can be tricky to assemble, it's easy to forget which way the seals go, etc etc, and at the end of the day, it's a survival critical part. if you stuff it up, you may find out about half a second before you die.

put it this way, as a mechanic (I almost put professional in there, but who am I kidding?), I will almost never rebuild a master cylinder (a) because the price of the kit plus assembly time will exceed the cost of a replacement (b) the risk of something going wrong, small though it might be, is too high.

doing it yourself at home is probably even more risky, unless you have a bore comparator, hone, seal picks, facilities to correctly clean, lubricate and assemble and test, then at best you're guessing that it's been done properly.

+ almost everything has Alloy bores in it these days & once they leak they are stuffed. They will not handle a rebuild without a sleeve.
