All right so my brakes are acting pretty inconsistent on hot days especially,they will fade like there is air in the lines,but I have bled them to no avail.Its wierd because if I stomp the brake or keep pretty taught pressure on it it will hold fine,but If I slowly apply pressure,like u would on any normal braking,it will slowsly slip to the floor,not all the way way,but pretty close.

So my question is do u think its seal on my master cylinder ,and if so is it re buildable,or is it one of those parts that u just replace.Im pretty sure the local machine shop/ parts house sells a rebuild kit for it,but not positive,I was looking for some insight first.Thanks


By the way I searched and found many similar threads,but none with the same problem as I am experiencing.

 

have you noticed it loosing fluid? If so look for leaks. If not that MIGHT be a good place to start. I'm not real sure if the ABS would make that happen.

 

This just happened to me.

If you're not loosing fluid then I would say its probably the brake master cylinder.

Beware! Mine did this right after I lost my clutch. Hopefully you've only got the one problem.

 

I'd put my money on the brake MC. They're nonservicable, so you have to replace them as a unit

 

yes its the MC, get it changed, ASAP, before you realize you have now become a passenger
