Chevrolet Cobalt Service & Repair Manual: Troubleshooting
| When troubleshooting the hydraulic
brake system, perform the following inspections. |
Master Cylinder Internal Fluid Leakage Check
| Start engine and depress the brake
pedal. If the pedal gradually falls under constant pressure, the hydraulic
system may be leaking. Raise the vehicle on a lift and inspect all tubing
lines and backing plates for signs of leakage. It may be required to lift
or remove the carpeting or floor mats to inspect for booster or master cylinder
leakage. |
Road Test
| When testing brakes, ensure the
road is level and dry. Test brakes at both light and heavy pedal pressure.
Do not lock up brakes or slide tires during a brake test. |
| Inspect the tires on the vehicle
before performing a brake test. Tires should be equally inflated, identical
in size and with equal tread pattern. Excessive camber and caster will cause
the brakes to pull. An overloaded vehicle will also brake erratically. |
