My brakes are pulsating up front as well. I took my calipers and pads off yesterday and cleaned the caliper out. I pumped my brakes without the pads installed and noticed the pots do not come out evenly (one of them came out only after I blocked the other 5 pots from moving. I'm thinking it's time to disassemble the caliper, remove the pots and seals, and just clean the be-jeezus out of everything before I lay down cash for some rotors.
I don't have a mityvac or speed bleeders... so, what are my options? I'm thinking I'll just empty the lines into a bucket, clean the calipers, reassemble, then slowly pour new dot 4 brake fluid into the master cylinder whist pumping the brake lever. When no more brake fluid will go in, I'll have to put the master lid back on, pump the lever, hold it in, then release the valve on the caliper and close it before letting the lever back out... (and doing this a BUNCH of times).
Sorry about the Hijack... but I'd like some confirmation from 'yall whether my method of refilling my brake fluid is acceptable without speed bleeders or a mityvac.
