When you are driving slowly with your foot off the brakes you will hear a scraping noise. The noise will go away when you apply the brakes. What you are hearing is the wear indicators making contact with the rotor surface after the pad lining have worn down to a certain level. Not all brakes uses wear indicators. VBD
There is a warning indicater on the brake pads to let you know they need replacing.
brakes do not release
The pads or shoes wear out and need replacing.
When you're brake pads be calm worn, they will have a slight shimmy when you apply the brakes. When the brake pads are completely worn out they will make a grinding noise.
Brake pads have audible wear tabs that make a screeching noise when the pads need replacing, some luxury cars(all bmws) have sensors that let you know when they need replacing.
No you dont have to. All I did was was pump the brakes with the car running
No, the brakes have nothing to do with the drive shaft.
Only if the rear system was opened where it may have gotten air in the lines.
brakes are over adjusted
To replace brakes effectively, you need to know what type of brakes you have. In general, you will need a jack, new brakes, a wrench and Allen wrenches.
They are equipped with a "telltale" warning that shrieks when the brakes are applied, with the brake pads are too low and need replacing.
They need replacing when they wear out. They could wear out at 23,000 miles if you drive hard with lots of stops or ride the brake with your foot. It is not normal for them to need replacing that quickly but it all depends on how you drive.
Brakes need adjusting? Pads need replacing? Caliper frozen? Low brake fluid level and need to be bled?
What do you need to know?
Inspect the brake pads. They are probably worn out and need replacing.
Your brakes are telling you they need replacing soon. They have a built in "squealer" designed to make a noise when the pad wear is nearing the end.
If you do not know how to do this then you should leave it to a mechanic. Replacing drum brakes is not an easy task anyways.
that depends on how often you drive. best way to determine if brakes need changing, is to look at brake fluid resevoir. if level is low, your linings are worn and either need replacing or renewing
If you are driving and you hear a high pitch squeeling/screaching sound but when you apply the brakes the sound stops your brakes need replacing, this is called your brake squeeler.
What about it? What do you need to know?
We need more info. Need to know the symptoms. Need to know what it does and does not do.
Try replacing your brake calipers.
If it is a Toyota, they do not know how to fix the squeaking brakes either. Even after replacing all the pads and machining the rotors and rear drums
when the old ones stop working
We would need to know what type of brakes you have... S-cam air brakes, air disc brakes, air piston brakes, air wedge brakes, hydraulic drum brakes, hydraulic disc brakes... they're all different.
