• Q: How to Service and Repair a Brake Caliper on 2002 Toyota MR2 Spyder?

  A: First service steps consist of separating the brake caliper structure by using pliers to eliminate the dust boot and sliding bushing followed by hammering the main pin boot with small screwdriver and hammer. Special Service Tool: 09719-14020 or 09719-00020 allows you to turn and counterclockwise remove the piston by following the removal process for cylinder boot set ring and cylinder boot. Proceed by loosening the 14 mm deep socket to set Special Service Tool: 09756-00010 on the adjusting bolt while keeping the spring area safe from potential injuries The snap ring comes off with snap ring pliers followed by the removal of parking brake strut, spring retainer, spring and spring plate while also taking out stopper alongside the adjusting bolt. Disassembly of the adjusting bolt assembly starts by replacing the Special Service Tool: 09756-00010 then proceed by removing the spring retainer, spring, spring seat, stopper and O-ring. Extract the torsion spring which rests within the parking brake crank before you take out both the parking brake crank along with its boot by using a small screwdriver alongside a hammer. Use a pin punch together with a hammer to remove the stopper pin while you also remove the bleeder plug, bolt and cable support bracket. Inspect pad lining thickness by using a 1.0 mm minimum and 10.0 mm standard and check disc thickness with a standard 16.0 mm and minimum requirement of 15.0 mm while measuring disc runout at no more than 0.10 mm. Adjust the disc runout by unmounting the bolts and torque plate for realigning the disk until it shows a minimum runout less than 0.10 mm. Reassemble by installing the stopper pin as well as the cable support bracket and bolt (torque 47 Nm) together with the bleeder plug (torque 8.3 Nm) while using Special Service Tool: 09612-22011 for the parking brake crank boot. Use the parking brake crank to complete the installation but make sure the needle roller bearing does not obviate the cylinder hole and perform the clearance check within 0.38 to 1.02 mm parameters. The adjusting bolt assembly needs a new O-ring with the torsion spring which should be installed and tightly secured using Special Service Tool: 09756-00010. Proceed to install the piston seal along with the piston through Special Service Tool: 09719-14020 (09719-00020). Ensure a correct alignment of the cylinder protrusion with the piston stopper groove. The installation process requires first placing the cylinder boot and set ring followed by main pin boot usage of Special Service Tool: 09325-12010 and finally placing the dust boot with sliding bushing inside.
