Note: When working on Tivs type calipers, use a Bendix or Girling type punch to remove the pad mounting studs, remove the clamps and press out the mounting studs.
3. Using pliers, press one of the pads and its piston into the cylinder cavity and remove the pad.
4. Conduct a defect inspection of the pad and, if necessary, replace all front brake pads.
