Hi everyone... I am having some serious issues with my brakes it all starts when my front left brake started squeeling so I went and bought some Duralast pads put em on CAKE.. So I thought well I pulled my car out of my garage and the front left was very tight rubbing badddd so it turns out the pins in my caliper were seized up and causing my rotor to slant therefore causing it to rub when the wheel was mounted I ended up breaking my caliper so I bought a brand new one well Ori*lys sold me a RH side caliper sure enough it bolted right up to the LH side took me two days an about $20 in brake fluid to figure it out so NOW I have the right caliper... I have bled the sh*t out of my brakes LH rear RH rear RH front LH front.. I bench bled the new caliper as well I've bled them three times since I've got the right caliper and no avail the pedal is stiff once bleeding is finished when car is off or on but a soon as I move the pedal sinks... I made sure brake fluid was topped off at all times pumped the brakes held pedal down opened bleeder til pedal sunk steady stream coming from every caliper.... Has ANYONE else have this problem any assistance anything I may have missed would be so appreciated!! Ps. There is no hissing or noise coming from the booster either?...

bleeding brakes can be a pain. did the master cylinder ever go empty? if it did your best beet is to get a vaccum pump on the bleeders and suck the air out. otherwize what i usually do is let the brakes bleed themselves. just open a bleeder screw and let fluid come out for 15 minutes or so then check the pedal

That's the last thing I can think of also when the pedal sinks if I push hard enough the RH front locks up and skids and the only time I didn't check the fluid level is when I took the caliper off the first time to pick up a new one but it didn't leak too much and during bleeding I kept it topped off I'm going to get some fluid tomorrow and let it sit with the bleeder screw open and see what happens I have never had so many problems over changing some brake pads lol I appreciate your help thank you
