BECUASE THE OTHER TIMES THEY ARE NOT NEEDED, AS IN ACCELERATION. SERIOUSLY, PLEASE BE MORE SPECIFIC.
I have a 2000 olds alero and the signal light only work sometimes, What would cause that?
Sometimes, the brakes don't work and there are flat tires.
You would probly have to do something with the wires i bet you have a short somewhere if there only working sometimes
This could be for a few reasons, but if they are getting hot without you applying them, I would suggest that they are sticking and causing the pads to rub on the discs, or if they are drum brakes, the shoes on the drums. If they are only getting hot as a result of using the brakes, I would suggest checking that the brakes are balanced properly, and that the front brakes are not doing all of the work/ or that the back brakes are working at all.
You can take your vehicle to Les Swab and they sometimes will give you a free brake inspection before doing any actual work to your brakes and charging you.
There are a few reasons that would cause your 2002 Pontiac back speakers to only work sometimes. The most common cause is a loose or corroded ground wire.
Pneumatic schematic in the air brakes in any type or build of truck all work in coordination with each other for smooth driving. The brakes would not be able to smoothly stop without them.
Check you brake fluid and lines. It may be as simple as bleeding your brakes.
If engine vacuum is low the brakes will be difficult to push. Sometimes, if the engine isn't running well when it's cold, the vacuum level will be low and the brakes won't work well. Have someone check that out for you.
2 wheel antilock brakes only work on the rear wheels, while 4 wheel antilock brakes work on all 4 wheels.
Brakes wear and require maintenance. They should always "work as well as they used to". When you detect a change in the braking have a trusted mechanic inspect them asap.
slowly push it along then pull the brakes, if it stops, THE BRAKES WORK!!! if it keeps going, THE BRAKES DON'T WORK!!! IT'S ROCKET SCIENCE!!!
