Tech Tip: Volvo Brake Goes Too Low on First Application

If a customer complains of Volvo brakes going too low on first application, it may be because of improperly installed brakes or aerated fluid.

Customer Concern: On first application the brake goes low, almost to the floor; after that the brake is OK.

Potential Causes: Improperly installed brakes; ­aerated fluid.

 

Tests/Procedures:

1. Check brake clips for proper installation. A mis-­installed clip will cause this problem. The bottom of the clip should go around the bottom of the caliper bracket.

2. Check for any air in the hydraulic system. Try bleeding with a pressure bleeder.

3. Bleed at the ABS hydraulic unit lines. Sometimes air can get trapped in this area, which is under the master cylinder.
