My rear brake is conking out on me.
In the last couple of months it's gotten very weak and spongy.
As I ride in winter, I figured one of the pistons has siezed as usual.
So I pulled it off and cleaned the pistons (they didn't seem to be siezed after all) and put it back on.
No difference, actually if anything a little worse.
So I figure it must be the hose getting weak and bulging (it's original). Put a new HEL braided hose on last week, bled the system.
No difference, actually if anything a little worse.
So that leaves two options. Either I really do have air in the system, or the master cylinder is knackered.
What are the chances of the master cylinder being worn out? It's a 2002 model with 20k miles.
I figure I can test it by removing the hose from the output of the master cylinder and plugging the port. If it's still spongy then it's the master cylinder, if it's firm then it's air. Will try this on the weekend.
Is it a better option to buy a used master cylinder off ebay or overhaul my own? Not that I can even find an overhaul kit. Any tips?
Cheers
