Geely Emgrand X7. Manual part — 384

8. Check the brake disc for run-out.

a. Install the front brake disc.

b. Tighten the brake disc with a special tool and hub

nuts.

Torque:125 Nm(Metric) 92.5 lb-ft(English
system)

c. Install the dial indicator on the shock absorber

away from the axle hub and rotating speed
sensor.

A dial indicator is used for measuring the brake
disc rub-out in the position of 13mm (0.53 in)
distancing from the edge of the brake disc.

NL06-0009b

Max. brake disc runout:0.005mm (0.002in)

Notes:

If the brake disc run-out exceeds the maximum, firstly change the mounting position of the brake disc and the axle
to minimize the brake disc run-out; if the brake disc run-out further exceeds the maximum after changing the
mounting position, inspect the upward clearance of the bearing and the run-out of the axle hub; if the bearing
clearance and the axle hub run-out are normal, or the thickness of the brake disc is within the specified range,
grind the brake disc; and if the brake disc is thinner than the minimum value, replace the brake disc.

Installation Procedure:

1. Align marks of brake disc and axle wheel hub,

and install brake disc.

2. Install brake caliper support fixing bolt and

tighten it.

Torque:30 Nm(Metric) 22.2 lb-ft(English system)

3. Install

brake

caliper.

4. Install brake pad.

5. Install the front wheels

6. Lower the vehicle.

Notes:

Similarly disassembly method of left/right front brake
disc.

6.3.2 Description and operation

6.3.2.1 Description and operation

Composition of rear disc-type brake system:

The rear wheel disk-type brake system consists of the following components:

Brake pad: the mechanical output force from the hydraulic brake caliper is acted on the friction surface of the
brake disc.

Brake pad guiding piece: located between the disc-type brake pad and the brake pad mounting bracket to keep the
brake pad moving smoothly, thereby eliminating noise.

Brake disc: the tire and wheel assembly is slowed down through the mechanical output force acted by the
disc-type brake pad on the brake disc friction surface for the braking of the vehicle.

Brake caliper: receive the hydraulic pressure from the brake master cylinder, convert the hydraulic pressure into
the mechanical output force to act on the internal brake pad, and enable the brake piston to automatically return
when the master cylinder returns.

Brake caliper and brake pad bracket: used for fixing the disc-type brake pad and the brake caliper in place to keep
in correct coordination with the hydraulic brake caliper. When mechanical output force plays the role on the brake
pad, slide the brake pad.

Disc-type brake caliper floating pin: used for mounting the hydraulic brake caliper and fixing the brake caliper in
place to keep correct coordination position with the brake caliper bracket. When mechanical output force affects,
the brake caliper is slid with respect to the braking filler block.

Operation of rear disc-type brake system:

The mechanical output force from the hydraulic brake caliper piston is acted on the internal brake pad; when the
piston pushes the internal brake pad outward, the brake caliper housing pulls the external brake pad inward at the
same time so as to uniformly distribute the output force; and the brake pad applies the output force to both friction
surfaces of the brake plate so as to slow down the tire and the wheel assembly. Whether the function of the brake
pad and the brake caliper component is normal is very important to uniformly distribute the brake force.
