2000 Toyota Tundra Parts Questions & Experts Answers

• Q: How to service and repair a brake caliper on 2000 Toyota Tundra?

  A: The brake caliper servicing begins with cylinder boot set removal using a screwdriver followed by preparing a wooden plate to secure the pistons between them and installing a pad on one side before using compressed air to remove pistons from the cylinder while ensuring finger safety in front of the pistons. Proceed to take out the 4 piston seals present within the cylinder. The pad lining thickness measurement with a ruler determines pad replacement; standard thickness stands at 11.5 mm (0.453 inch) and minimum thickness requires 1.0 mm (0.039 inch) thickness. Pad replacement is needed if minimum requirements are not met or when uneven wear is detected. A micrometer should measure the disc thickness at 28.0 mm (1.102 inch) as the standard and 26.0 mm (1.024 inch) as the minimum specification; any disc requiring replacement must also be free of scores or uneven wear patterns. A dial indicator should be used for disc runout measurements at a spot 10 mm (0.39 inch) from outside edge limitations with a maximum 0.07 mm (0.0028 inch) variation; a new disc needs replacement except when grinding with an "On-Car" brake lathe after front hub bearing play inspection verifies specifications. The procedure for disc runout correction requires looseness of hub nuts and disc followed by disc installation at one-sixth of its original position while torquing hub nuts to 113 Nm before performing another runout measurement. Continuation of this process aims to establish minimum runout values less than maximum limits and replacement of the disc if adjustment fails. Disassembly must be reversed for reassembly while the technicians apply lithium soap base glycol grease and disc brake grease to specific parts.
