1996 Chevrolet Camaro Brake Service (ONLINE REPAIR MANUALS)

This rear caliper, Fig. , consists of a single piston and an aluminum housing which is suspended in a mounting bracket through two slide pins. Hydraulic pressure, created by applying force to the brake pedal, acts equally against the piston and the bottom of the caliper bore to move the piston outward. This action slides the caliper inward, resulting in a clamping action on the brake rotor. This clamping act...

Brake Roughness

The most common cause of brake chatter on disc brakes is a variation in thickness of the disc. 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 check for this condition, measure the disc at 12 points with a micrometer at a radius approximately one inch from edge of disc. If thic...

System Operation

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, init...

Master Cylinder Overhaul

Except Aurora, Bonneville, Corvette, LeSabre, Park Avenue, Riviera, 88 & 98

Disassemble

Refer to Figs. and when performing the following procedures.

• Remove master cylinder from vehicle as follows:
• Disconnect and plug hydraulic lines.
• Remove two master cylinder attaching nuts, then the master cylinder.
• Remove reservoir cover and diaphragm. Discard old brake fluid in reservoir.
• Inspect cover and diaphragm. Replace if cut, cracked or deformed.
• Remove fluid level switch, if equipped.
• On models with compact master cylinder, remove proportioner valve assembly, Fig. ...

Caliper Removal

• Disable parking brake automatic adjuster as follows:
• Working from inside vehicle, remove driver seat cushion, then the parking brake lever cover screws and cover.
• Using .080 inch gauge wire, fabricate a tool to disengage drive pawl from sector, Fig. .
• Using tool mentioned above, disengage drive pawl from sector, then insert a nail through anchor plate to keep drive pawl in disengaged position.
• Pull up on lever until it aligns with pawl, then depress button until lever is fully downward.
• Visually inspect that anchor plate is fully against stud. If not, repeat procedure ...

AC-Delco Tandem Diaphragm Type

This unit utilizes a vacuum power chamber, consisting of a front and rear shell, housing divider, front and rear diaphragm, plate assemblies, hydraulic pushrod and a diaphragm return spring, Figs. and .

In normal operating mode, with service brakes in released position, the booster operates with vacuum on both sides of its diaphragms. When brakes are applied, air at atmospheric pressure is admitted to one side of each diaphragm to provide power assist. When the service brake is released, atmospheric air is shut off from one side of each diaphragm. The a...
