![]() But, Toyota and GM do not recommend this procedure.ĥ. You can restrict the brake hose with a non-damaging toolĪnd relieve the pressure through the bleeder. Do not use force to screw the piston into the disc brake cylinder. Push back the piston with the appropriate tool. Remove caliper bolts that hold it to the knuckle.Ĥ. Remove the pad guide pins and disc brake pads and shims.ģ. Remove the clip, anti-rattle spring no.1 and anti-rattle spring no.2.Ģ. Always install a new copper washers with the union bolt.ġ. Note: If the caliper was replaced, the torque for the union bolt is 29 n/m or 21 ft/lbs. Torque the lug nuts to 103 n/m or 76 ft/lbs. Torque the two bolts to 34.3 n/m or 25 ft/lbs.ġ5. Note: Install the pad wear indicator plate facing upward.ġ4. Depending on the type of shim used on the new brake pad, lubricate the recommended areas as indicated by the manufacturer. Install the caliper bracket and torque the bolts to 106.8 n/m or 79 ft/lbs.ġ3. Apply the lithium or silicone base lubricant to seal the surface of slide pin’s dust boots.ġ2. To remove or install the pins, Toyota recommends using a socket (19 mm) and hammer to drive the dust boots into the disc brake cylinder mounting. It is recommended that the slides and bushings in the bracket be replaced if the rubber or metal has degraded. You can also apply a moly-based lubricant to the surfaces that make contact with backing plate of the brake pad. Clean the bracket and replace the abutment clips if necessary. This can make a more thermally stable rotor that absorbs heat evenly and reduces pulsation comebacks.ġ1. ![]() With this technique you can minimize the amount of material removed from the rotor during on-the-car machining. Tip: You can lower the runout by changing the position of the rotor on the hub flange. If the disc runout is the maximum value or greater, check the bearing play hub flange runout. Toyota specifies a maximum disc runout 0.05 mm (0.0020 in.). ![]() Measure the rotor’s runout 10 mm away from the outer edge of the disc. Make “matchmarks” on the front disc and the axle hub. The standard thickness is 25 mm (0.984”). Inspect caliper bracket for damage and corrosion.Ĩ. Remove the bolts that hold on the caliper bracket.ħ. Using a ruler, measure the pad lining thickness. Make a note of the positions of all four shims and clips.ĥ. If the pads are original, it will have a two-piece shim on each pad. However, Toyota does not recommend this procedure.Ĥ. You can restrict the brake hose with a non-damaging tool and relieve the pressure through the bleeder. Remove the outer pad and push back the piston with the appropriate tool. Inspect the piston boot for any damage.ģ. Pull the caliper and hang it from the strut. While these vehicles are not prone to abnormal brake noise, Toyota advises in TSBs that technicians should pay attention to hardware and shims when performing a brake job.Ģ. Looking at the TSBs from Toyota’s website, these are relatively trouble free with no recalls for the brake system. While others say it was to simplify production. Some say it was due to better ABS systems. No official explanation could be found for the change.
