The rear brakes of a 1998 Lexus GS300 are equipped with anti-squeal shims, which makes them different than other brakes you may have worked with. The process of replacing them is still simple and will only take about 15 minutes per wheel. The GS300 brake pads should be inspected every 15,000 miles or whenever trouble is suspected. Replacement pads are stocked or can be ordered at most auto-parts shops.
Instructions
- 1
Loosen the lug nuts. Lift the wheel off the ground with a jack and remove the wheel. The jack point is several inches in front of the wheel and is marked by a notch on either side.
2Remove the two bolts that hold the caliper in place. The bolts are on the back side of the caliper assembly. Lift the caliper off the disc and suspend it with a piece of wire. Do not let the caliper hang from the brake line.
3Remove the two anti-squeal springs, four shims and the two pads. The shims and pads are rectangular and held in place by the spring and a guide pin. Pry with a flat-head screwdriver if necessary.
4Spread disc brake grease on both sides of the inner shims. Attach the shims to the replacement pads.
5Install the pads and retain them with the anti-squeal spring.
6Press the piston into the cylinder using something convenient such as a hammer handle.
7Remove the caliper from the suspending wire and slide it into place. Install the bolts, tightening to 77 ft- lbs. of torque. Replace the wheel and lower the car.
