I replaced my front brake pads on my gt-four, I forced in the pistons one at a time, I dont know if that caused an issue, I bled the brakes today, got out all bubbles. Went for test run, and same thing. Long as I'm driving below 5000rpm its fine, as long I give it some beans the pedal with sink right to the floor and barely slow down with a swervy feeling. Please someone help me kindasad.gif

to clear up some thoughts, I bled lines completely and also did a master cylinder test, xhut off engine, apply pressure to brake pedal, and it does not sink, there is enough fluid in the resovoir, I just dont get what could be the problem, unless air have gotten into the abs system somehow. :S

Im not sure but it could be your brake booster going out. I had a civic with the same thing happening. I replaced the brake booster and it was back to working condition.

I managed to get it slightly better I pushed in two pistons at a time bleed off the fluid that was forced, I was able to get some bubbles out, brakes is now performing better, but not back to normal, will try doing this to all four calipers instead of just the front and see if it solves my problem completely
