Hello!
I recently had to replace pistons and seals on my rear caliper as the rear brake completely failed.
While I was taking it all to pieces, I thought replace the brake line and seals in the master cylinder.
Brake line not a problem, seals in the master cylinder on the other hand are like rocking horse s..t!
I went into my local biker shop, they aren't listed unless you got to Yamaha which are 50 a set.
Anyone had a similar experience? Do they ever fail? Is that why they aren't around or common as others?
I am wondering if after stripping the plunger, etc out of the cylinder perhaps I should just rebuild it and hope a clean out was all it needed.
