I checked my front brake the other day because I felt the braking power was not there and I was hearing some rubbing -- found what looks to be 4 - dots of mineral oil on the back of the pads (2 on each side - were the pistons contact the pad). I cleaned it up and re-lubed the pistons with mineral oil. The braking power was still not there so I changed out the pads and it came back -- but I am worried now that the pistions have a slight leak.
I have put the contaminated pads on with the pad spacer - and clamped the brake up overnight -- is this a good enough test as to whether or not the pistions are leaking? I plan to see what I find after work tonight.
So I am wondering:
- Any rebuild kits out there with new seals?
- If I relube the pistions with a 100% silicone lube (brand recommedation) -- could that help seal them better
- Is it possible I have the reservoir too overfilled?
