Air brakes are located in the front of a truck or trailer. There are many parts to an air brake. If you suspect a problem, you need to take your truck to get fixed.
What to do if you have a problem with the brakes on the Town and Country van
vauxhalls do have brakes what is the problem with them ? what model ?
They can if the brakes are out of adjustment or have a mechanical problem.
Light is usually comes on, when there is a problem with pressure in brake lines. Inspect the brake fluid level, and check for leaks.
If your ABS emergency brake light and the track control light show up on the dashboard, you are having a brake problem.
Problem?
No, they use air pressure or actually the lack of air pressure to stop the vehicle. The brakes are fully on until pressure builds up in the tank releasing the brakes. When you push the brake pedal this removes air from the system and applies the brakes.
Leading brakes are the primary braking system. ON a car, for example, the front breaks apply more braking force than the rear (trailing) brakes do. There is a slight difference in this pressure so a vehicle does not brake out of control.
If this is a recent problem then it may be stuck wheel clinders / calipers , causing the brakes to overhaet or a brake pressure problem. if you have a abs system on your car then it will have to be taken in for serive if it involves the abs system. iIf you just installed brakes then try bleeding and adjusting your brakes, if they have an adjustment.
HA NO BRAKES!!!!
