  Q: How to overhaul the front brake calipers on Chevrolet Aveo?

  A:

  Start by removing the whole caliper assembly then disconnect the caliper guide pin between the Piston housing and retaining frame. Next take out the bleeder valve protector and the bleeder valve itself. Pull out the pins along with the rubber boots and take off both the brakes pad and pad springs from inside the caliper. Always use safety glasses when operating compressed air to shield your eyes from damage. Also keep your fingers behind the caliper pistons when using compressed air as the Piston(s) travel with strong force and could harm you; insert a wood block inside the caliper housing to prevent the Piston from ejecting. Push the Piston out with compressed air from the housing before taking off its inner and outer seals from their places in the caliper Piston bore. Warm all components in brake fluid or denatured alcohol before cleaning them with dry non-oiled compressed air. Use air to clear passages inside the housing and the bleeder valve. Check the Piston and caliper components for damage then replace anything that shows signs of condition problems. Also test and maintain the caliper bleeder valve performance. Do not use hand tools or other equipment to change Piston dimensions in the caliper or Piston area. Insert the new Piston inner seal into the caliper housing groove and make sure the twist is eliminated before placing the outer Piston dust seal in its designated groove. Push the Piston into the bore after greasing it with brake fluid and check that the dust seal fits properly into its groove. Apply rubber grease to pins and add the boots before putting the dust cap and bleeder valve into place. Secure the bleeder valve at 6 nm (53 inch lbs.). Position the Brake Pads and pad springs correctly before putting on the retaining frame to the caliper housing with guide pin bolts. Clamp all bolts to 27 nm (20 ft. Lbs.). Finally, install the caliper assembly.

  Q: How to replace the Brake Calipers on Chevrolet Aveo?

  A:

  Vehicle service begins with support systems and marks that show wheel positions to the Wheel Hubs before brake wheel removal follows with proper brake dust protection. After removing the brake hose washers and fitting from its caliper connection it becomes necessary to disconnect the hose and apply plugs to both the caliper and the brake hose to stop fluid leaks and prevent contamination. First disconnect the caliper mounting bolts from the Steering Knuckle before removing the caliper assembly. Before fitting the slide pins you must apply silicone brake lubricant from gm p/n 89021536 or ac delco p/n 89021537 or canadian p/n 89021538. Fasten the caliper assembly with its mounting bolts to a torque of 95 n.m (70 lb ft). When installing the brake hose use washers for attachment to the caliper then tighten it to 40 n.m (30 lb ft). After wheel placement lower the vehicle until you obtain a firm Brake Pedal which ensures your safety before movement. Use the off engine state to perform multiple Brake Pedal applications which will locate the caliper piston and pads before proceeding with brake system bleeding.
