I hit my breaks the other night and they went almost to the floor, there are no leaksand the fluid is still full so i thought it was the master cylinder so i took one off of a parts car and still the same problem , the only break that is working is the drivers front, when i bleed the master cylinder i only get fluid out of one side, any sugestions?

well thats not making total sense here


with ABS it can be a nightmare to bleed these witohut re-homing the two pistons cylinders on the ABS unit or you will not get anything out of the rear lines

was there brake fluid in the large vacuum hose to the vacuum booster?

if so then the old master cylinder rear piston seal was blown
