i started with rebuilding my old front wheel cylinders. this worked good for two days untill the car started pulling to the left when you hit the brakes.
attempt #2
so, i bought new cylinders (raybestos), put them in, bleed everything. went for a drive and they worked for a while but the longer i went the softer they became, after it sat overnight i had drips on both tires.
Attempt #3
i pulled everything and one cylinder on each weel seemed to be taking on air. i thought it was at the supply hose. ordered and installed new hoses, put it all back together. rebleed everything had good pressure, took it for a spin two days later the pedel had to be pumped to get pressure. and i had a puddle at both wheels....
attempt #4
when the wife applied pressure to the brake pedel on the ruturn you could hear a hissing sound from the top two cylinders. i didnt know if it was a bad seal or if they were taking air at the hose so i pulled everything, installed a rebuild kit that i had lying around and put hydralic thread sealer on all hoses re bleed everything had good pressure. it was two late for a test drive so i thought i would wait till next day.... this morning i had two new puddles and had to pump the pedel to get pressure. rock automotive said they would return the two faulty cylinders but im about to give up on these things i am tired of pulling everything apart reassembling it , rebleeding, and re adjusting the toe and heel.... im thinking it time for the midus touch..
what could i be doing wrong? could i really have got 4 bad cylinders at once?
