Q: How to replace the front brake pads on Cadillac Escalade?
A: Test the brake master cylinder reservoir before work; you can keep fluid levels unchanged when the reservoir sits at middle marks between top and bottom limits. Before working lift the vehicle and take out the tire with its attached wheel. Check brake caliper functionality and hold it in place through wire support to shield the brake hose from damage. Detach the caliper from its mounting bracket keeping the hydraulic brake hose linked, then push out the brake pads from the mounting bracket and throw away the anti-rattle clips. Examine the caliper brakes and connecting bracket before putting new anti-rattle clips onto both bracket sides and Brake Pad surfaces. Place the brake caliper first then wheel assembly before taking away safety measures during the vehicle descent. Press the Brake Pedal to its two-thirds mark while turning off the engine then release the pressure gradually to fully position brake caliper parts. Complete service by filling the brake fluid reservoir with fresh fluid then running the brake system to smooth out Brake Pad metal contacts on disc rotors.
Q: How to replace the rear disc brake pads (J56) on Cadillac CTS?
A: Before working on rear disc brake pads (J56) check the brake master cylinder fluid level. If the fluid sits at midpoint between marks you can continue without fluid removal. When the fluid level is above midpoint drain it until it reaches midway position. Lift the vehicle and take out all parts from the wheel assembly so you can start work. Take off the lower Brake Pad guide pin and Brake Pad spring before removing the upper Brake Pad guide pin and brake pads. Insert the brake caliper pistons into their bores with a spreader tool when they are fully in position. Replace any guide pins that show damage or corrosion instead of trying to clean them. Rephrase the brake piston boot when it shows clear signs of damage. Force the Brake Pad guide pin into the brake caliper housing until it reaches its complete position. Use the Brake Pad spring and lower guide pin to pass through the brake caliper before sliding over its edge to ensure proper installation. Place the tire wheel back onto the vehicle. Depress the brake pedal with an engine turned off until it reaches 2/3rd of its total motion and let the pedal return slowly. Press and hold the brake pedal for 15 seconds then release it before repeating the action till the brake pedal response becomes solid and pistons pad placement is complete. Complete the brake system by adding fluid then using a special tool to prepare new brake pads and rotors.
Q: How to replace the front brake pads on Cadillac XLR?
A: Check the brake fluid level in the master cylinder before starting work. If the fluid is at the center between maximum and minimum lines, no fluid needs to be drained but excess should be reduced to the center if fluid is above the mid-point. When raising the vehicle lift up the tire and wheel assembly before removing it. Apply your hands to thread a wheel lug nut to lock the rotor onto the hub. Insert the old inner Brake Pad or wood block against the caliper pistons under large c-clamp pressure until the pistons push through the brake rotor. Use mechanic's wire to prevent damage to the brake hose as you unplug the upper bracket and take out the guide pin bolt of the caliper portion. Lower the caliper onto its mounts without distorting the hose before checking pad retainers and brake pads when they are removed. When the slides show signs of damage replace them right away. Install the large c-clamp again to push brake pistons all the way home. Remove both the pad and clamp from their positions. Fit Brake Pad retainers and new pads on the rotor. Position the Brake Pad wear sensor towards the rear when you rotate the brake rotor in forward motion. Push the brake caliper up into the holder space before adding the upper guide pin bolt. Tighten the bolt to a torque of 31 nm (23 ft. Lbs.). Put on the tire and wheel assembly while lowering the vehicle and utilize the brake pedal without power to activate it halfway then release slowly. Release the brake pedal for 15 seconds and do this test until the brake pedal feels solid. This action positions both caliper pistons and brake pads correctly. End the process by filling the brake reservoir until it reaches the correct level and running the system to smooth out the brake pads and rotors.
