Brake system - bleed (Brakes)

6. Position suitable spacers and secure brake disc using wheel nuts. Tighten wheel nuts to 70 Nm.
7. Set dial test indicator 6 mm from disc outer edge.
8. Measure disc run-out: Run-out limit = 0.05 mm.
9. If run-out exceeds limit, mark disc to show position on drive flange; remove 2 screws retaining disc, remove disc and refit after rotating 180°. Tighten disc securing screws to 7 Nm and re-check disc run-out.
10. Renew disc if run-out exceeds limit even after re-positioning of disc on drive flange.
11. Untie caliper and support caliper weight.
12. Align caliper carrier to hub ensuring correct positioning of brake pads. Fit and tighten bolts to 85 Nm.
13. Apply foot brake several times to enable brake pads to position correctly.
14. Remove wheel nuts and spacers.
15. Fit road wheel(s) and tighten nuts to correct torque. See INFORMATION, Torque wrench settings.
16. Remove stand(s) and lower vehicle.

BRAKE SYSTEM - BLEED

Service repair no - 70.25.02

The following procedure covers bleeding the complete system but where only the primary or secondary circuit have been disturbed, partial bleeding is permissible if a brake pipe or hose has been disconnected with only minor loss of fluid.

CAUTION:

• Never re-use fluid that has been bled from the brake system.
• Do not allow fluid level in master cylinder to fall below ’MIN’ level during bleeding.
• Do not fill reservoir above ’MAX’ level.

1. Raise front and rear of vehicle.

WARNING: Support on safety stands.

2. Check all pipe and hose connections are tight and there are no signs of leakage.
3. Top-up fluid level in brake reservoir to ’MAX’ mark. See INFORMATION, Capacities, fluids and lubricants.

CAUTION: Use only NEW brake fluid of the recommended grade.

Bleed sequence - non ABS and ABS systems: LH rear to RH rear RH front to LH front

CAUTION: Braking efficiency may be seriously impaired if wrong bleed sequence is used.
