Visual inspection of hydraulic system components (Chevrolet Tahoe 2)

1. Remove the wheel, secure the brake disc with wheel nuts and inspect the area around the caliper piston dust boots (2).



2. If there are obvious signs of leakage, repair or replace the brake caliper.

3. When the brake system is stationary, remember the position of the piston (4) relative to the caliper body (1).

4. Ask an assistant to press and release the brake pedal several times, while observing the operation of the brake caliper: the pistons should smoothly and evenly extend (5) and retract (6) into the caliper.

5. If the pistons (1) move unevenly, the piston seal (3) may be damaged, repair or replace the caliper.
