1992 Ford Bronco Brake Service (ONLINE REPAIR MANUALS)

Normal Hydro-Boost units will produce certain noises that current technology cannot correct. These noises occur when brake pedal is manipulated in a manner not associated with everyday braking habits. Normal operating noise can be a hissing, clunk, click or a chatter.

If above normal pedal efforts are applied, the Hydro-Boost unit will emit hissing noises. These noises will be particularly noticeable with the vehicle motionless and will increase in intensity as pedal efforts increase and system operating temperatures increase. Loud hissing noises at or below normal pedal effo...

Bleed primary and secondary hydraulic brake systems separately, bleeding the longest line first on each system. Do not allow reservoir to run dry during bleeding operation. Never reuse fluid that has been drained from the hydraulic system. Ensure proper bleed sequence is followed.

On Aerostar, Bronco, E-Series, Explorer, F-Series and Ranger models, the bleed order is right rear, left rear, right front, left front.

On Villager models, the bleed order is left front, right front, left rear, right rear.

• Loosen master cylinder to hydraulic line nuts and wrap sho...

Aerostar, Explorer & Ranger

• Remove caliper as described under "Caliper Service," leaving brake hose connected.
• Secure caliper with wire so that caliper is not hanging with weight on brake hose.
• Compress anti-rattle clip, then remove inner pad from caliper.
• Press each ear of outer pad away from caliper, slide torque buttons out of retention notches and slide pad off caliper.
• Reverse procedure to install, noting the following:
• Use an eight inch C-clamp and a worn inner pad or block of wood to bottom out caliper piston in bore.
• Install new anti-rattle clip on lower end of inner pad.
• Refill...

The rear anti-lock brake system (RABS) constantly monitors rear wheel speed. In the event of an impending rear brake lockup, the system regulates hydraulic pressure to the rear brakes, preventing total lockup when the brakes are applied and thereby reducing the possibility of skidding.

The system consists of a yellow warning light on the instrument panel, an electro-hydraulic rear anti-lock brake system (RABS) valve mounted on the frame rail behind the crossmember, a speed sensor mounted on the rear drive axle, an exciter ring mounted on the differential case and a computer module. O...

Brake Linings

Remove both front wheels and inspect the brake discs, calipers and linings. (Wheel bearings should be inspected at this time and repacked if necessary).

Do not get any oil or grease on the linings. It is recommended that both front wheel sets be replaced whenever a respective shoe and lining is worn or damaged. Inspect and, if necessary, replace rear brake linings also.

If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.

Brake Roughness

The most common cause of brake chatter on disc brakes is a variation in thickness of ...
