Brake Pedal Vibration and Grinding from Brakes on Acura RL

The 1999-2004 Acura RL has brake caliper issues, which are known for causing vibration and grinding noises at all times.

The brake rotor is a disk that sits between two brake pads. The brake pads are squeezed against the disk by what is called a brake caliper. When that caliper gets stuck, the brake pads are permanently pressed against the rotor causing:

• Vibration in brake pedal
• Vibration on steering wheel
• Illumination of the ABSor brake warning light
• Grinding noise from one corner of the vehicle
• Vehicle pulls to one side of the road
• Braking requires more pressure on the brake pedal

The repair for a seized brake caliper, the brake pads, brake rotor, and brake caliper must be replaced or vibration will remain after the new caliper is installed. Changing the brake fluid and flushing the brake system according to manufacturer specified intervals can help improve longevity of the brake caliper.
