Front Wheel Heating Problem

[thusira]

Hi

I have a 2007 toyota vitz and i noticed a while back after 1 hour driver the rim of front wheel getting very heat than the rear. front wheel has disk break. What could be the reason for this ?

Also the break booster is fine.

is it normal in vitz the speed u get is reduced quickly when you take the leg from the accelerator out ?

thanks,

Thusira

A brake bind occurs when air trapped inside the brake system expand as the brake system heats up. As a result of the expanding air, the brake pads/shoes are pushed towards the rotor/drum thus producing friction among the two surfaces. This produces heat. It's like driving while keeping your foot on the brake pedal the whole time.

The front brakes heat up quite a bit, especially on a front wheel driven vehicle and even more on a front wheel driven automatic. To determine if your brakes are actually binding, you can do the following test.

- Drive the car about until you feel like the brakes are starting to bind

- Jack up one of the front wheels

- Making sure that the handbrake is in place, put the car into neutral

- Try spinning the front wheel by hand

- Repeat with other front wheel

If you could spin the wheel normally, then your brakes are probably okay. If the wheel refuses to spin and seems to be locked in place, your brakes are binding. There are other reasons for the wheels to lock up besides a brake bind caused by air bubbles in the brake lines. A stuck brake caliper also might be an issue.

It's normal for the front brakes to heat up than the rear I guess, but not beyond a certain point. And according to the symptoms that you have described (car slowing down quickly when accelerator is released), it does sound like there is a slight brake bind.

- Was a brake repair done recently?

- How's the condition (and level) of your brake oil?

- Substandard brake shoes have a tendency to get stuck within the caliper although this is very rare. How are the brake shoes?

If everything above is normal, bleed your brake system and top up with new oil. Air trapped inside the brake system can cause brakes to bind.

thanks,

Was a brake repair done recently? the previous owner has replaced the tires of front

How's the condition (and level) of your brake oil? clear and fit to the level

How are the brake shoes? did not check yet.

does breaks bind produce heat ?

what is the certain point u mentioned ?
