The most common cause for a vehicle to shake when the brake is applied is a worn or warped rotor. Other causes include bad shock absorbers, worn bushings or degraded suspension components.Know More
RepairPal experts state that distortions as small as three or four one-thousandths of an inch in size can cause the brake pedal to pulse, and make the whole vehicle shake. The rotor works by clamping down on the wheel and applying friction to slow the vehicle down. A tremendous amount of heat is generated during this process, and temperatures can exceed 500 degrees. Over time, the exposure to heat wears away at the rotor. To determine if a worn rotor is the cause of the vibration, the rotors are measured for uniform thickness and run-out.
A damaged rotor is repaired by machining it on a brake lathe. Resurfacing the rotor eliminates defects causing the vibration, but also thins the surface rendering it more vulnerable to heat exposure. If the rotor is too badly damaged to machine, the mechanic will replace it. While the sensation is unsettling, according to Autohub360, the issue is more of an annoyance than a safety hazard because the brakes themselves are not affected. If the mechanic does not find distortions in the rotors, the problem may be due to worn bushings or wear and tear to the suspension.Learn more about Brakes
Drum brakes work by pressing brake shoes against the inside of a drum-shaped cylinder attached to the wheel of the vehicle. The friction produced by this contact slows the wheel, slowing down the vehicle. Drum brakes are most common on older vehicles. On newer vehicles, they are often attached to only the rear wheels, and more-efficient disc brakes slow the front wheels.Full Answer >
To add brake fluid to a vehicle, clean the reservoir cover, open the reservoir, check the fluid level and fill the reservoir to the indicated level. If the vehicle is equipped with an antilock braking system, check the owner's manual for special instructions before opening the cap.Full Answer >
A vehicle may stall when someone hits the brakes due to problems with the transmitter throttle trim, low speed needle, clutch spring, engine idle speed and brake linage. Some of the issues require part replacement and some require adjustments.Full Answer >
If the steering wheel or car shakes when the brakes are applied, it is almost certain that the problem lies with the rotors. This is an important distinction as steering wheel or car vibration can happen for a number of reasons, but if it only happens when the brakes are applied, this isolates the problem. Worn brake pads are another possibility, but if the pads have recently been replaced, then this leaves only the rotors as suspects.Full Answer >
