After driving a while I loose the brake pressure. Then it seems to come back.
I have 2001 Dodge Caravan, just replaced the front pads and rotors. Need Help

Thanks

Sounds like you may have air in the system. Try bleeding front and rear brakes. If the brake are doing the same thing, you may need a master cylinder.

 

I have bleed the brakes, my understanding is if a master cylinder goes it goes. Does not come back and forth, good to bad. Interesting conversation about the fluid boiling if a caliper is sticking, changing the viscocity of the fluid causing the pedal to go down then grab once pumped slightly. Checked the caliper and moving freely. For the fluid to get real hot friction would have to be there. What if the bearings were starting to wear and the heat was hot enough to transfer to the mounting bracket for the caliper causing the caliper to get hot to boil the fluid. I have ran through all other diagnostics to solve this problem. Time to trade it off.

Thanks
