Disc Brakes -> AC-Delco Single Piston Front Disc Brake -> Troubleshooting -> Brake Roughness
Vehicle: 1999 Pontiac Sunfire 2.4 L4 GAS
Brake Roughness
The most common cause of brake chatter on disc brakes is a variation in disc thickness. If roughness or vibration is encountered during highway operation or if pedal pulsation is experienced at low speeds, the disc may have excessive thickness variation. To inspect for this condition, measure the disc at 12 points with a micrometer at a radius approximately one inch from edge of disc. If thickness measurements vary by more than ...

Drum Brakes -> Type 1 -> Adjustments -> Parking Brake -> Service Brake
Vehicle: 1999 Pontiac Sunfire 2.4 L4 GAS
These brakes have self-adjusting shoe mechanisms that ensure proper lining-to-drum clearances at all times. The automatic adjusters operate only when the brakes are applied as the vehicle is moving rearward.
An initial adjustment is required after the brake shoes have been relined or replaced, or when the length of the adjusting screw has been changed during service operations.
Frequent usage of an automatic transmission forward range to halt reverse vehicle motion may prevent the automatic adjusters from functioning, thereby inducing low pedal heights. Should low pedal heights be enc...

Vehicle: 1999 Pontiac Sunfire 2.4 L4 GAS
Front & Rear Split System
When the brake pedal is depressed, both the primary (front brake) and the secondary (rear brake) master cylinder pistons are moved simultaneously to exert hydraulic fluid pressure on their respective systems.
If the rear (secondary) brake system fails, initial brake pedal movement will cause the unrestricted secondary piston to bottom in the master cylinder bore. Primary piston movement will displace hydraulic fluid in the primary section of the master cylinder to actuate the front brake system.
If the front (primary) brake system fails, initial brake pedal mo...
