I converted the front brakes to discs. Now, you have to pump the brakes to get them to work. When you first step on the brake, it goes all the way to the floor. After pumping once, the brakes feel tight and stop well. I have bled and bled and bled the brakes and they are still doing that.
If you dont have a leak/air in the system and your rear brakes are adjusted up properly...You need a master cylender.
The calipers are on the correct side. I will have to check for a leak. The brakes worked fine before I switched to discs, maybe it is because it is still the drum brake master cylinder.
If you're using rear calipers which have a worm screw parking brake assembly {Granadas had this} the parking brake has to be adjusted so the pads barely come in contact with the rotor....If not, the pistons retract too far into their bore and it needs that first push of the pedal to cover the distance
Me too... sounds like an adjustment problem. If the pedal pumps up 2x and gets very hard, more likely adjustment, If it pumps up but still has some give, it's more likely air.
did I misunderstand? do you still have drums on the rear? If you have discs on the rear, the adjustment mentioned above applies if you have that particular setup. a loose rear adjustment will make the shoes expand further than the stroke of the pedal will allow. when you pump them up, they seat which is why the pedal will eventually get hard(if this is the case). the return springs will pull them back over time forcing fluid back to the master cyl so that the pedal has to be pumped the next time, repeating the process.
If u still have problem after adjusting the drums; I say like Mavman2 "Think New Master Cyl". If ur brake hoses and whl cylinders are of unknown age, I wud replace those too. Better to do it all at once and be thru with it. IMO.
