Well today, i was stopping from 65 to make a 90* turn right, all in about 65 ft. But the car wouldn't stop, at first the brakes had effect but really fast i had the pedal all the way to the floor and i wasn't stopping quickly enough. I soon stopped later and smell burn something, dont think i burn the brakes, but the car wouldn't stop. so i tried it again five minutes later, this time 70 to a dead stop. Yet the car wouldn't stop, i had to let off and keep going then stop...


How can i prevent this from happening again?

This has never happened to me before but i am normally not slowing down that quickly from that speed ever....


Thanks

 

Sounds as though you more than boiling fluid, those stops unless really frequent should not make the fluid boil.

Verify you have no vacuum leaks, and check the fluid level. pads, etc.

 

This is not fluid fade.

If you smelled something it may be a leak in the system spraying on a hot surface.

When you say the brakes were on the floor, do you mean that the pedal went to the floor? If that is the case it is a bad mastercylinder or you have a leak somewhere.

This will only get worse unless fixed.

If the pedal did not move, then check for a vacume leak or bad booster.

good luck

 

wow

 

I was running metal to metal for like 1000 miles and then my fluid boiled and burst the caliper piston seal, but yeah that was like two weeks ago.

 

I've found that synthetic brake fluid works wonders on my car for fluid fade. Most people don't realize that conventional brake fluid picks up moisture and that lowers the boiling point. Anytime I do the brakes, I change out all the fluid in the bowl before starting and again when I'm done.

 

that's the design of modern brake fluid- it's hygroscopic. It soaks up water on purpose.

 

Even synthetic brake fluid soaks up water still. I run it though. Its only like $5/quart so I don't have a problem running it. Forgot what brand I'm running though. I'm gonna go run out and take pics of my C4HD brakes though so I'll check and post back.

EDIT: Just checked, I'm running Valvoline SynPower fluid. Seems to work well. The brakes are very responsive with that running through the Earl's lines to the twin-piston calipers

 

That's the same fluid I've been running for the last 10 years and I love it. However, My 89 Nissan pickup - parts getter hates it!!!! I had to change calipers, and wheel cylinders after using it. Of course California's MTBE gasoline ate up the rubber in the fuel lines so it's probably just a Nissan thing.....
