  Q: How to overhaul the front brake calipers on Cadillac Catera?

  A:

  Time your work on the brake caliper front by separating the Piston from its housing carefully while avoiding placing your fingers ahead of the Piston before applying compressed air because this action ejects the Piston with great force which puts you at risk of injury. After inserting a strip of wood or a shop towel inside the caliper you should feed moderate compressed air into the housing inlet hole. Replace the Piston due to performance issues when you discover any damage or flaws on its surface. You must use a small wood or plastic device to uncouple both the dust boot and seal of the front brake caliper from its housing. Test the caliper housing bore and seal groove for damage but use crocus cloth first before replacing it due to light corrosion. Put all components in denatured alcohol to clean them. Use unlubricated compressed air to dry them after that. Compressed air should be blown through all passages and the valve housing as the last step of cleaning. Put the Piston into the bore groove of the housing with brake fluid and position the dust boot properly before sealing it tight. Position the Piston in front of the dust boot before blowing compressed air through inlet bore of the caliper housing to expand the boot around the Piston. Releasing compressed air when putting the Piston into the caliper housing will push the boot into the machined channel on the Piston.

  Q: How to replace the front brake calipers on Cadillac Catera?

  A:

  A mechanic must begin by raising the vehicle before they or he can remove the tire and wheel to change the front brake caliper. Open the bleeder screw while you attach a tube to drain fluid into a container but prevent reverse contamination of improper fluid entering the brake system. Push the Piston into the caliper housing bore to open space between the linings and rotor. Remove the brake hose bolt while discarding both the front hose and its seals by throwing them away. First, remove the guide pin bolts from the caliper bracket then take out the caliper. Check the brake pads for uneven wear and maximum taper of 0.15 mm (0.006 inch) since failure to meet specs requires pad replacement. To replace the brake pads disconnect the Brake Pad wear sensor electrical connector and harness retainers from the front suspension strut while making sure you don't pry the sensor from the Brake Pad because you need to push it out instead. You should pull off the inner Brake Pad with sensor attached before proceeding to extract brake pads and the Brake Pad wear sensor through the caliper bracket with a small punch. Prior to installation maintain clean and lubricated conditions for front Brake Caliper Bracket mounting surfaces. Attach the Brake Pad wear sensor onto the inner Brake Pad while connecting the harness and retaining components to the front suspension strut and refastening the electrical connector. If brake pads were removed reinstall them into the caliper bracket before installing the caliper . Tighten the guide pin bolts to 30 nm (22 ft. Lbs.) during new bolt installation.the procedure requires installation of the front brake hose alongside new front brake hose seals afterward. Secure the new front brake hose bolt with 40 nm (30 ft. Lbs.) torque value. Bleed the hydraulic brake system before you install the tire and wheel and lower the vehicle. Twenty controlled stops at 48 km/h (30 mph) with medium to firm brake pedal pressure will allow the brake rotors to burn in properly before you heat them up too much.
