Mirage Sedan DE L4-1468cc 1.5L SOHC MFI (1997)
Brake Caliper: Testing and Inspection
Measuring Brake Drag Force
1. Measure the rotary-sliding resistance of the hub by the following procedure with the pads removed.
2. Remove the drive shaft. Refer to "Drive Axles, Bearings and Joints."
3. Attach tool No. MB990998, or equivalent to the front hub assembly as shown in the illustration, and torque to 177 - 275 Nm (130 - 203 ft. lbs.)
4. Use a spring scale to measure the rotary-sliding resistance of the hub in the forward direction.
5. After installing the caliper support to the knuckle, install the pad clips and the pads to the caliper support.
CAUTION: Do not let any oil, grease or other contamination get onto the friction surfaces of the pads and brake discs.
6. Be careful that the piston boot does not become caught when lowering the caliper assembly, and torque the slide pin (M14 bolt) to 83 - 93 Nm (61
- 69 ft. lbs.)
7. Start the engine and then depress the brake pedal 2 - 3 times.
8. Stop engine and turn brake disc forward 10 times.
9. Use a spring scale to measure the rotation sliding resistance of the hub in the forward direction.
10. Calculate the drag force of the disc brake (difference between of values measured in step 9 and step 1). The standard value is 59 N (13 lbs.) or
less.
11. If the drag force of the disc brake exceeds the standard value, disassemble piston and clean piston. Check for corrosion or worn piston seal, and
check the sliding condition of the slide pins. Replace as necessary.
