  Q: How to replace the front Brake Pad Set on Toyota MR2 Spyder?

  A:

  You need to take away the front wheel before mounting the hub nuts to hold the disc in place while replacing front brake pads. Use the caliper inspection hole to check pad lining thickness before pad replacement because minimum thickness should be 1.0 mm (0.039 inch). If the pad does not reach this standard then install new pads. Apply tooling to break loose the bolt securing the flexible hose from the front Shock Absorber. You should lift the caliper while maintaining hold of the sliding pin and unfastening the bottom-side bolt but keeping the flexible hose connected to the Brake Caliper before safely suspending the caliper. You should take out all the pads together with their associated components such as the four anti-squeal shims and two pad support plates. While these can be reused if they appear normal with no deformation damage or cracks and remain rust-free and clean of dirt along with foreign substances. The two pad support plates must be installed correctly while checking the disc thickness and runout values. To install new pads, users must replace anti-squeal shims at the same time they should apply disc brake grease on outer-facing inner anti-squeal shims and then install two anti-squeal shims on both pads' inside and outside surfaces while placing inside pads with worn indicator plates downward before installing outer pads without oil or grease touching the friction surfaces. Push the piston into position with a hammer handle tool after removing a small brake fluid portion from the reservoir and if resistance occurs use the bleeder plug to drain fluid until pushing is possible. Install the cylinder onto the torque plate with the bottom-side bolt while holding the sliding pin before torquing the bolt to 34 Nm (350 kgf-cm, 25 ft. lbs.). Install the flexible hose to the shock absorber followed by installing the bolt while torquing it to 29 Nm with 296 kgf-cm or 21 ft. lbs. of torque. To finalize the installation you need to apply torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.) to the front wheel then you should depress the brake pedal a few times before checking that fluid reaches the max line.

  Q: How to replace the rear Brake Pad Set on Toyota MR2 Spyder?

  A:

  Starting the rear brake pads replacement process begins by removing the rear wheel while keeping the disc fastened with hub nuts. The inspection hole of the caliper lets you check pad lining thickness so you must replace the pads when they reach 1.0 mm (0.039 inch) below the minimum length. The parking brake cable removal process begins with unclipping the cable while simultaneously extracting the cable pin and rotating the parking brake crank before disconnection. The bolt should be removed to disconnect the flexible hose from the Shock Absorber. Wedge the caliper by taking out the installation bolt on its bottom side yet maintain the flexible hose connection to the caliper and hang it safely. Take out the two pads together with four anti-squeal shims before removing the four pad support plates for reuse only when they are free of rust, dirt, have no signs of wear and no deformation or cracks. The disc thickness requires inspection before installing the four pad support plates but make sure these plates do not get mistaken for the wrong order. Take new pads to specification then replace the anti-squeal shims at the same time; spread disc brake grease across both sides of every inner anti-squeal shim before installing two outer shims and two inner shims followed by the outside pad with the wear indicator plate facing up and the inside pad. The Special Service Tool: 09719-14020 (09719-00020) should be used to turn the piston clockwise at a slow pace until it becomes free. This movement should align the cylinder protrusion with the piston stopper groove while pads should be replaced one wheel at a time to avoid the opposite piston escaping. Position the pad protrusion through the piston stopper groove before securing the caliper but avoid damaging the dust boot and flexible hose. After this secure the installation bolt with 20 Nm torque (204 kgf-cm, 15 ft. lbs.). The flexible hose should connect to the shock absorber before installing the bolt at 29 Nm (296 kgf-cm, 21 ft. lbs.). Reestablish the parking brake cable but start by installing the clip followed by the pin as you operate the parking brake crank. Finish by mounting the rear wheel at 103 Nm (1,050 kgf-cm, 76 ft. lbs.). After the installation of new brake fluid you should check that the fluid reaches the highest mark on the fluid reservoir.
