The first thing you need to take into consideration is that if you sense any kind of problems with your brakes, you shouldn’t be driving your car at all. Pull over and check it out before you go on, otherwise you will risk getting into an accident because your brakes might not perform as they should. A common problem is sticky brakes; after releasing the brake pedal, you keep on sensing some sort of pressure applied on the wheels. Another sign might be that your brakes don’t work as they should and it takes a long while for your car to get to a complete halt after you have pressed down the brakes completely.
Checking your Brakes
If you sense something is wrong with the brakes, then you need to check them immediately. The way to do it is to first remove the wheels. To do that, you will need two wrenches: a standard wrench and a wheel-nut wrench that has an extension bar for easier manipulation. Then you will need a car jack to get a better look at the brake pads.
After the wheel is removed, you will need to unscrew the brake pads and check them out. Most will have a certain indicator showing you if they’re worn out or not. If the indicator shows that they are, you need to replace them immediately.
After you’ve replaced the pads, take your car for a spin round the block and keep it running at a low speed so you don’t risk getting into an accident. Does the problem still persist? If so, you will probably need to check for something else, like the master cylinder.
Master Cylinder Problems
A very common problem with sticky brakes is caused by a faulty master cylinder. While you shouldn’t attempt to replace it on your own, you can check if everything is working properly and then decide on the appropriate measure to take.
This cylinder is responsible for transforming the mechanical force you apply when pushing the brake into hydraulic pressure. The pressure then moves the caliper pistons, and it might be that the seals, which maintain that pressure at a regular level, don’t slide in the housing properly. If so, the piston will not respond accordingly and push the pads on the wheels, generating heat and causing them to lock up. If that is the case, you need to have the master cylinder replaced.
