How to Adjust a Mazda 3 E-Brake

The Mazda 3 is equipped with a 4-wheel disc brake system that features a mechanical actuator, built into the rear brake calipers, for e-brake assembly adjustment. This feature expands the caliper piston when the e-brake lever is pulled to ensure proper brake pad clearance and e-brake function. An initial adjustment of the e-brake cable may be necessary in addition to normal service procedures to compensate for normal wear of the cable.

Instructions

1

Place wheel chocks in front of and behind the right front tire. Raise the left rear wheel using the floor jack positioned on the reinforced lifting point found along the lower edge of the Mazda's body in front of the rear wheel opening. Slip a jack stand under the rear sub-frame to provide added safety.

2

Locate the small plastic adjustment access cover in the rear of the center console. Lift it out of the console using a small screwdriver to gain access to the adjusting nut located underneath it.

3

Lift up on the e-brake lever until it clicks three to five times. Screw the adjuster nut clockwise until the brake pads clamp tightly on the rotor and the rear wheel can not be spun by hand.

4

Release the e-brake lever and verify that the wheel now turns smoothly. Remove the jack stand and lower the floor jack. Remove the wheel chocks and test drive the Mazda 3 to verify the brakes work correctly and the parking brake holds the vehicle when applied.
