So I gradually began losing pressure in my clutch on the 07 EXC525. I popped the cylinder cover and sure enough....NO FLUID. I followed the directions in the manual and added the mineral oil, bled it, and it worked for 1 day. No pressure the next day. I pull the cover off the cylinder and the rubber gasket inside is literally swollen to twice its size. I then find out I'm not supposed to use mineral oil AS IT STATES in the owner's manual. So today I put in DOT 4 BRAKE FLUID with the new rubber gasket and STILL NO PRESSURE WHATSOEVER! I'm getting kinda frustrated with it. Is it possible my cylinder is bad? I only have 1K miles on the bloody thing! Any feedback appreciated.
