Hyundai Genesis: Brake System / Rear Disc Brake Repair procedures
1. |
Remove the rear wheel & tire.
Tightening torque:
88.3 ~ 107.9 N.m (9.0 ~ 11.0 kgf.m, 65.1 ~ 79.6 lb-ft)
|
|
2. |
Loosen the guide rod bolt (B) and pivot the caliper up out of the way.

4. |
Loosen the hose eyebolt (B) and caliper mounting bolts (C), then remove the rear caliper assembly (A).
Tightening torque :
Brake hose to caliper (C) : 24.5 ~ 29.4 N.m (2.5 ~ 3.0 kgf.m, 18.1 ~ 21.7 lb-ft)
Caliper assembly to knuckle (A) : 78.5 ~ 98.1 N.m (8.0 ~ 10.0 kgf.m, 57.9 ~ 72.3 lb-ft)

Rear Brake Disc Thickness Check
1. |
Check the brake pads for wear and fade. |
2. |
Check the brake disc for damage and cracks. |
3. |
Remove all rust and contaminating materials from the surface,
and measure the disc thickness at the place of 5mm from the outer
circumference as the illustration below.
Standard value :
13 mm (0.5118 in)
Service limit :
11.4 mm (0.4488 in)
Deviation: less than 0.005 mm (0.0002 in)
|
If wear exceeds the limit, replace the discs and pad assembly on the left and right of the vehicle. |
Rear Brake Pad Check
1. |
Check the pad wear. Measure the pad thickness and replace it, if it is less than the specified value.
Pad thickness
Standard value: 10 mm (0.3937 in)
Service limit : 8.0 mm (0.3149 in)
|
|
2. |
Check that grease is applied to sliding contact points, and check the pad and backing metal for damage.
The brake pad wear indicator and brake disc make a friction
noise when brake pads are worn out below the service limit of 2.0 mm. |
|
Rear Brake Disc Runout Check
1. |
Place a dial gauge about 5mm (0.2 in.) from the outer circumference of the brake disc, and measure the runout of the disc.
Brake disc runout
Limit : 0.025mm (0.00098 in.)
|
|
2. |
If the runout of the brake disc exceeds the limit specification, replace the disc, and then measure the runout again. |
3. |
If the runout exceeds the limit specification, install the
brake disc after turning it 180° and then check the runout of the brake
disc again. |
4. |
If the runout cannot be corrected by changing the position of the brake disc, replace the brake disc. |
1. |
To install, reverse the removal procedure. |
2. |
Use a SST (09581-11000) when installing the brake caliper assembly. |
3. |
After installation, bleed the brake system.
