Hi,

Was trying to bleed the brake system on Minerva and on retightening the bleed nipple managed to break off the back of the cylinder, obviously it wasn't in great condition. My question is should I replace both brake cylinders or is it safe to just replace the one?

Thanks

Philip

As long as the other wheel cylinder is operating OK, then it should be alright to replace only the damaged one.
Looking at the damaged cylinder, is it a fault in the casting that's caused the break or was the material just very weak for some reason?
Bleed nipples shouldn't be overtightened otherwise the seating surfaces can be damaged.

I think it was just a fault in the casting as the whole of the back broke off.

You don't say whether it's front or rear. If it's one of the front cylinders, and you're having to change one, renew the other at the same time.

Personally I prefer to replace the cylinders as an axle set, all 4 at the front or both of the rears, especially if you dont know how old the originals are.
