breaks failing

By ikon
- Wed Jun 24, 2009 1:52 am #125417 i autox everyweek and i ive noticed lately that once my breaks heat up they tend to not work anymore. the petal will give some tension but when i press hard it goes right to the floor. once the car has cooled the pedal will give me a little more push back but will still hit the floor which sucks cuz then i have no breaks if i have to come to a comlete stop fast. its my daily driver and i need to race friday cuz im in a time attack series. any suggestions as to what the problem could b and how to fix it?

if not... then it might be the master going out. feels spongy i guess

- Wed Jun 24, 2009 3:16 am #125433 the breaks r stock and i just replaced the pads and flushed the fluid and then drained the system. i doubt its that though. i believe its the brake master cylinder or a leak in the lines that gets worse when the lines r hot and they expand. the whole setup is stock.

- Wed Jun 24, 2009 4:09 am #125441 ya mine's all stock as well. i run 1/4 mile on friday nights and do my fair share of "spirited" daily driving.

only does it after driving a while though. and the system is completely bled and leak free. i hope it's the master, that's easy enough.

- Wed Aug 05, 2009 4:32 pm #135677 you mentioned draining and replcing the old brake fluid. there might still be air trapped inside the system. try bleeding the brake system first as just to eliminate this possibility. it wouldn't cost you a cent. :)

unless he is racin nacars there is no point to upgrade form dot 3 to
dot 4,5 or even 5.1 will actually mess the brake system up.
