Remove the Old Caliper

• 1). Cut off the vehicle's power for safety. Disconnect the cable from the negative battery terminal.
  
  
• 2). Drain two thirds of the brake fluid from the master cylinder. Discard the old fluid and have fresh fluid ready for later.
  
  
• 3). Remove the tire and wheel assembly once the car is raised and stable. Mark where the wheel and wheel stud should reconnect. Secure the rotor to the hub with two wheel nuts.
  
  
• 4). Compress the caliper piston with a C-clamp or the equivalent. Make sure the piston bottoms in the bore.
  
  
• 5). Disconnect the brake hose from the caliper by removing the inlet fitting bolt. Plug the hose and holes in the caliper.
  
  
• 6). Take out the caliper, first by removing the mounting bolts. You should then pivot the caliper assembly up so it clears the rotor and slide it inboard off the pin sleeve.
  
  

Install the New Caliper

• 1). Install the new caliper body assembly. Holding it in the position of the old one, work the pin boot's large end into the caliper body groove, push the assembly onto the pin and move it into position.
  
  
• 2). Attach the mounting bolts back onto the caliper. On the 15 series Escalade, tighten the guide pin bolts to 31 foot pounds. Tighten them to 80 foot pounds on the 25 series model.
  
  
• 3). Connect the brake hose at the caliper by installing the inlet fitting bolt. Tighten the bolt to 33 foot pounds.
  
  
• 4). Bleed the brake system to remove air from within. Open the bleeder valve and press down on the brake pedal.
  
  
• 5). Reattach the tire and wheel assembly. Refill the brake master cylinder with fresh fluid. Reconnect the battery cable to the negative terminal.
