How to Replace Brake Pads on an Aveo

Iskandar Blogger 4:39 AM

The braking system on the Chevrolet Aveo consists of the brake fluid, master cylinder, brake caliper, brake pads and rotors. When the driver pushes the brake pedal down, the fluid travels through the brake lines and pressurizes the cylinder inside of the brake caliper. The cylinder then compresses the outer brake pad against the rotor. This tightens the caliper around the brake rotor, which stops the car. When the brake pads wear down to the wear indicators inside each pad, the pads need to be replaced.

Instructions

    1

    Park the car on a level surface and engage the emergency brake.

    2

    Loosen the front driver side and front passenger side wheels with the lug wrench.

    3

    Slide the jack up under the front and jack the car up from a safe spot, such as the cross frame below the engine. Position the jack stands under the front jack points on both sides of the Aveo. Lower the car so that it is sitting on the stands. Leave the jack under the car in the upright position as an extra safety measure.

    4

    Unscrew the lug nuts from the front driver side and front passenger side wheels. Pull the wheels off and set them to the side.

    5

    Move back to the front passenger side and remove the two mounting bolts from the back side of the brake caliper with the ratchet. Turn the bolts counterclockwise and remove them.

    6

    Slide the tip of the flathead screwdriver into the top of the brake caliper. Pry the caliper back and forth to loosen it.

    7

    Pull the brake caliper off of the rotor. Place the caliper onto the lower control arm on the back side of the wheel.

    8

    Pull the inner brake pad out of the caliper. Insert the C-clamp and compress the outer brake pad toward the caliper cylinder. Continue to turn the clamp until the caliper cylinder is completely inside the brake caliper. Remove the clamp and the outer brake pad. Remove any other brake pad parts, such as clips and shims.

    9

    Put the new brake pads with the new accessories into the brake caliper. Put the brake caliper back onto the rotor. Screw the bolts back in place and tighten the bolts with the ratchet and socket. Put the wheel back on, along with the lug nuts. Tighten the lug nuts with the lug wrench.

    10

    Lower the car. Crank the engine and push the brake pedal in and out five or six times to match the new brake pads up with the brake rotors.
