Perform this adjustment with the wheel off. If not, the guide pins will come off and the caliper will be damaged when the brakes are applied.Īdjusting Rear Drums 1. The clip should be fully inserted into the guide pin no. (b) Insert the other clip end into the hole of the guide pin no. Fix guide pins with clip (a) Insert the clip end into the hole of the guide pin no. (b) Hook the spring lower portion to the center hole of the pad. (a) Hook the spring upper portion to the guide pin no. (a) Hook the spring upper portion to the guide pin no.1.

Install the two guide pins to the brake pads. Depending on the type of shim used on the new brake pad, lubricate the recommended areas as indicated by the manufacturer. Place the caliper on over the rotor and install the mounting bolts and torque to 46.6 n/m or 34 ft/lbs. Apply the lithium or silicone based grease to sealing surfaces of the boots. This can make a more thermally stable rotor that absorbs heat evenly and can reduce pulsation complaints. With this technique you can minimize the amount of material that is removed from the rotor. Also, 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 in the axial direction and check the hub flange for runout. Measure the disc runout 10 mm away from the outer edge of the disc. Using a ruler, measure the pad lining thickness. Remove the bushings and slides from the caliper assembly so they can be replaced or cleaned and lubricated. But, Toyota and GM do not recommend this procedure. You can restrict the brake hose with a non-damaging tool and 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. Remove the pad guide pins and disc brake pads and shims. Remove the clip, anti-rattle spring no.1 and anti-rattle spring no.2. Always install a new copper washers with the union bolt.

* 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. Note: Install the pad wear indicator plate facing upward. Install the caliper bracket and torque the bolts to 106.8 n/m or 79 ft/lbs. Apply the lithium or silicone base lubricant to seal surface of slide pin’s dust boots. 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.

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.

Remove the bolts that hold on the caliper bracket. Make a note of the positions of all four shims and clips. If the pads are original, it will have a two-piece shim on each pad. But, GM nor Toyota does not recommend this procedure. Remove the outer pad and push back the piston with the appropriate tool. Pull the caliper and hang it from the strut. While these vehicles are not prone to abnormal brake noise, both GM and Toyota have advise on their sites that technicians should pay attention to hardware and shims when performing a brake job.

Looking at the TSBs from the manufacturers’ websites, both the Vibe and Matrix are relatively trouble free with no recalls for the brake system.
