How to Adjust an Emergency Brake on a Lexus RX 330

The braking system is an important safety feature on a vehicle that requires constant monitoring and proper maintenance. A seldom used but important component of the braking system is the emergency brake. Failure problems with the emergency brake are usually discovered during inspections by a mechanic or by government certification authorities. On the Lexus RX 330, such problems can be fixed by adjusting the emergency brake.

Instructions

1

Put your Lexus in neutral, disengage the emergency brake, and place chock blocks around the front tires.

2

Lift both rear wheels of the vehicle off the ground, loosen the lug nuts and remove the wheels. Starting with the left rear of the vehicle, locate one of the 8 millimeter access holes in the rear brake disc drum and turn the drum so that the access hole is at the 6 o'clock position. Using a flashlight, locate the emergency brake adjustment gear through the disc drum. It is immediately behind the disc drum and is star-shaped. Insert a flathead screwdriver into the brake adjustment gear opening and turn clockwise until the disc drum resists spinning. Reinstall the wheel.

3

Proceed to the right side of the vehicle and repeat the same procedure for other wheel.

4

Test the emergency brake by parking your vehicle on a slope and engaging the emergency brake.
