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
When the brake pads come in contact with the brake rotor to slow and stop a vehicle, the pressure and friction occasionally cause a vibration that produces a squeaking sound. These squeaks are often normal, but they may also mean that the brakes are starting to wear out.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 brake pedal on a vehicle becomes hard to press, its resistance could be related to a number of different problems, including an obstruction of the brake lines or an issue with the brake booster. Some common problems associated with brake boosters include defective check valves and leaky vacuum hoses.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 >
