Quick backdrop on my situation,

I purchased the car about a year ago and the brake pads were all replaced. Over time, the brakes got very sponge like and rebled the brakes almost 4+ times.

When its cold outside, the brake pedal will be solid. However I noticed that when it starts to increase in temperature outside, the pedal will sometime become sponge like.

I rebled the brakes one more time, and I keep running into the same problem over time.

Hopefully the brake booster isnt going out (symptoms usually are its hard to press the brakes, mine are the opposite) or the master cylinder is going out.

P.S. I've always checked the MC for the fluid and its always at full. Haven't refilled it once after rebleeding.

Any advice?

Thanks in advance,
Jon

 

no clue?

 

I haveE THE SAME PROBLEM but it doesnt stop me fro driving the car its just that its annoying !

 

any others? Looking for a solution.

 

I don't know why it happens when it's warm, but maybe you should look into a new MC. Also, check to see if your rears need adjusted. That can help with a spongy pedal, and give your e-brake a more responsive feel.

 

ill try that out - hmm. I guess I could go ahead and upgrade my MC to a 15/16 for bigger brakes in the future lol.

But ill check out the brakes this weekend.

 

bump for any other comments?

 

try changing the master cylinder and if not that then the booster???...
maybe
