Lateral runout inspection 

1. To secure the disc plate and the hub, tighten the hub nuts upside down or insert a washer (thickness 10 

mm {0.39 in} with an inner diameter more than 12 mm {0.47 in}) between the hub bolt and the hub nut. 

2. After tightening all the hub nuts to the same torque, put the dial gauge on the friction surface of disc plate 

10 mm {0.39 in} from the disc plate edge.  

3. Rotate the disc plate one time and measure the runout. 

Front disc plate runout limit 0.05 mm {0.002 in}  

Thickness variation inspection 

1. Clean the disc plate-to-pad friction surface using a brake cleaner. 

NOTE:



The component parts of the SST (49 B017 001 or 49 G019 003) can be 
used as a suitable washer.

2. Measure the points indicated in the illustration using a caliper (micrometer)  

3. Subtract the minimum value from the maximum. 



If the result is not within specification, machine the disc plate using a lathe. 

Thickness variation limit 0.015 mm {0.0005 in}  

DISC PLATE THICKNESS INSPECTION 

1. Measure the thickness of the disc plate. 



If the thickness is not within the specification, replace the disc plate. 

Minimum front disc plate thickness 26 mm {1.03 in}  

Minimum front disc plate thickness after machining using a brake lathe on-vehicle 26.8 mm 
{1.06 in}  

DISC PAD THICKNESS INSPECTION 

1. Jack up the front of the vehicle and support it with safety stands.  

2. Remove the wheels.  

3. Verify the remaining thickness of the pads. 



Replace the pads as a set: right and left wheels, if either one is at or less than the minimum 
thickness.  

Minimum front disc pad thickness 2.0 mm {0.08 in}

WARNING:



Do not exceed minimum disc plate thickness.

vehicle then machined. Machine the disc plate while installed on the 
vehicle.

FRONT BRAKE (DISC) REMOVAL/INSTALLATION 

1. Remove in the order indicated in the table.  

2. Install in the reverse order of removal.  

3. After installation, add brake fluid, bleed the air, and inspect for fluid leakage. (See AIR BLEEDING.)  

4. After installation, depress the brake pedal a few times, rotate the wheel by hand, and verify that the brake 

does not drag.
