DISC PLATE MACHINING

id041100802100

Caution

•  Do not install disc plates that are less than the minimum thickness specified. Do not machine a disc plate below the minimum thickness specification.

1.  Inspect wheel bearing runout and correct if necessary.

2.  Remove the wheels and tires.

Note

•  Begin at the front of the vehicle unless the vibration is isolated to the rear.

3.  Remove the caliper.

4.  Inspect the brake pad. If below specification, replace the brake pad with a new one. (See DISC PAD (FRONT) REPLACEMENT.)

5.  Measure and record the disc plate thickness. After machining, if the disc plate is at or below specification, replace with a new one. The specification is stamped on the disc plate. Do not machine a new disc plate.

6.  For vehicles equipped with a two-piece hub and brake disc component:

(1)   Place an alignment mark before disassembly.

(2)  Remove the disc plate.

(3)  Using a die grinder with a mild abrasive, remove any rust or corrosion from the wheel hub and disc plate mounting surfaces.

(4)  Align the alignment marks and reinstall the brake disc on the hub.

7.  Using the special tool, machine the disc plates. After machining, verify that the disc plate meets the thickness specification.

Caution

•  Do not use a bench lathe to machine disc plates.

Note

•  The depth of the cut must be between 0.10—0.20 mm {0.004—0.007 in}. Lighter cuts will cause heat and wear. Heavier cuts will cause a poor disc plate surface finish.

8.  Using a dial gauge, verify that the disc plate lateral runout is now within specification.

9.  Remove the hub adapter.

10.  Remove any remaining metal chips from the machining operation.

11.  For vehicles equipped with a two-piece hub and brake disc component:

(1)  Remove the disc plate from the wheel hub.

(2)  Remove any remaining metal chips from the wheel hub and disc plate mounting surfaces and from the ABS wheel-speed sensor.

(3)  Apply a high temperature anti-seize lubricant to the mounting surfaces.

(4)  Align the alignment marks and install the disc plate to the wheel hub.

12.  Install the caliper. (See CALIPER (FRONT) REMOVAL/INSTALLATION.)

13.  Install the tire and wheel assembly. (See WHEEL AND TIRE REMOVAL/INSTALLATION.)

14.  Verify that the brake system operates normally.
