How to service and repair a brake caliper on 2003 Toyota Tundra?

Question

Accepted Answer

Service and repair of the brake caliper requires first removing all four cylinder boot set rings and boots with the help of a screwdriver. Create a wooden plate to support the pistons inserted between the components with a pad mounted on one side followed by compressed air usage to extract opposite pistons from the cylinder while retaining fingers outside the operational zone. The 4 piston seals in the cylinder must be removed using a screwdriver. Use a ruler to check pad lining thickness because the standard is 11.5 mm (0.453 inch) and the minimum is 1.0 mm (0.039 inch); discard the pad when it falls under the minimum or shows uneven wear. A micrometer should measure the disc thickness for inspection. The disc needs replacement when its thickness falls below 26.0 mm (1.024 inch) or there is any scoring or uneven wear. Measure the disc runout using a dial indicator at 10 mm (0.39 inch) from the outside edge. The maximum allowable runout stands at 0.07 mm (0.0028 inch). Disc replacement is needed if the runout exceeds this value but grinding the disc on a "On-Car" brake lathe remains an option provided that front hub bearing play meets specifications before the measurement process begins. Disc runout can be optimally positioned by removing the hub nuts and disc and reinstalling the disc 1/6 of a turn from its original position and torquing the hub nuts to 113 Nm (1,150 kgf-cm, 83 ft. lbs.) before repeating runout measurement until optimal positioning is achieved. Place the disc in the position which shows the minimum runout results unless the maximum runout readings come first; in this case, choose another disc because the original one should be discarded. Reassembly proceeds as an inverse process of disassembly where lithium soap base glycol grease and disc brake grease should be applied to the designated parts.
