Ok so I had my car up on stands for like.. close to 4 months.. I just finally got my suspension on and now i'm having a weird intermittent brake problem..

I start the car up, put foot on brake, pedal feel is fine.. i backe dit down my driveway and pedal went to the floor with hardly ANY braking power. I let up to turn the car to the left and then pressed the brake really hard expecting it to floor again, and pedal feel was normal. This happened 3-4 times in the past couple of days while I have been moving my car in/out of the garage.

Any ideas? Could my coilovers be pinching the front brake lines causing this? Its not leaking a drop so nothing is torn or broken..

I will bleed them tonite and throw new brake fluid in to see if that helps. Air bubble maybe?

Any ideas?

Sounds like a master cylinder going bad. 95% chance that's your problem.

 

Its Brake Disc in the 4 wheels? cuz if it is your problem is in the presure distributor or your master clinder like the other guy said

 

Make sure your axle nut is tight. I had that problem and the rotor would kind of flop around and push the pistion back. IT would feel soft till the pistion settled the rotor back.

 

It's probably your Master Cylinder like the first guy said. Are the brakelines pinched? If they are, that's your problem. Otherwise, try taking apart the whole brake assembly, and put it back together. See what happens, but I'm guessing somehow, there's lots of air in your brakelines....and that's not good.

 

air in the lines or brake master cylinder.
try bleeding the lines first. if this isn't the cure then it is the master cylinder.
