HAIMA 7 - Removal and Installation of Front Disc Brakes

Check of front disc brakes
P-11
2. After all hub nuts screwed up to the same torque, place the dial gauge on the friction surface of brake
disc, at ca.,10 mm{0.39 in} away from the edge of disc.
3. Turn once the brake disc and measure the lateral run-out.
Run-out limit: 0.05 mm {0.002 in}.
1. Clean up with brake cleaner the friction
surfaces of brake disc and brake pad.
2. Measure, with a micrometer calipers, the
thickness of each point as shown in the figure.
3. Subtract, with the measured maximum value the
minimum value. If the result is nonconforming
to the requirements, process the brake disc with
grinding tool.
Variation limit of thickness: 0.015 mm {0.0005
in}
Warning
Don’t surpass the requirements of minimal brake disc
thickness.
Check the variation of thickness
Check the thickness of brake disc
Attention
If the disc is removed from the vehicle for processing, it will result in excessive run-out, thus the disc shall be
processed when fitted up on the vehicle.
1. Measure the thickness of disc. Replace the disc when the disc thickness is not within the range of
technique requirements, then,
The minimal thickness limit of front brake disc: 24 mm {0.94 in}
The minimal thickness limit of rear brake disc: 10 mm {0.39 in}
Check the thickness of brake pad
1. Jack up the front part of vehicle and shore it up
with the safety bracket.
2. Remove the wheel.
3. Check the residual thickness of pad and replace
the pad by full set. As long as the thickness of
one lateral pad of R/L wheels is less than or
equal to the requirement of minimal thickness,
the pads at both sides should be replaced at the
same time.
Pad thickness required: minimum value: 2.0 mm
{0.08in}
Removal and installation of front disc brakes
1. Remove in the order as shown in the Table
2. Assemble in the reversing order of disassembly
3. After installation step down the brake pedal several times, turn manually the wheel to confirm that no
brake blocking exists.
