Antilock Brakes - Shop Manual Revision
86ford17 Article No. 86-10-2ANTI-LOCK BRAKE - SHOP MANUAL REVISION
LINCOLN-MERCURY 1986 CONTINENTAL, MARK VII
This article is published to provide additions and corrections to the procedures outlined in Section 12-29 of the 1986 Car Shop Manual, Volume B, when servicing the Anti-Lock Brake System.
Hydraulic Reservoir Description - Page 12-29-4 First paragraph should read:
Figure 1:
The reservoir is mounted to the brake booster at three locations: 1) A screw at the mounting bracket. 2) A push-in tube outlet that seats in a grommet located in the brake booster. 3) A push-in stud and grommet that seats on the brake booster. (Figure 1)
Hydraulic Reservoir Removal - Page 12-29-10 Step 7 (Last Step on page) should read:
7. Pry the reservoir from the brake booster housing by placing a flat screwdriver between the push-in tube outlet and the push-in stud and grommet (Figure 1). Pry up gently and check to be sure that the short sleeve and O-ring are removed from the booster grommet hole.
Hydraulic Reservoir Installation - Page 12-29-11 Steps 1 through 10 should read:
1. Install the reservoir mounting bracket in its guide on the bottom of the reservoir.
2. Check to see that the spacer sleeve and O-ring are in place on the reservoir.
3. Make certain that the rubber grommet is on the stud. (Figure 1)
4. Wet the booster housing grommet and the stud grommet with the brake fluid.
5. Install reservoir on the brake booster. The reservoir should be held in a vertical position and pushed straight down into the booster housing grommet and stud support holes as far as it will go. Be sure the sleeve and O-ring are in place on the reservoir outlet tube.
6. Secure the mounting bracket to the booster housing with the allen head screw. Tighten the screw to 4-6 N-m (35-53 in.lbs.).
7. Install the return and pump feed hoses onto the reservoir fittings as far as they will go.
8. Fill the reservoir to the MAX line with brake fluid and bleed the brake system as outlined.
9. Top off the reservoir to the MAX line with a fully charged accumulator.
10. Install reservoir cap and connect the electrical connector.
11. Connect battery ground cable.
Solenoid Valve Block Assembly Removal and Installation - Pages 12-29-9 and 12-29-10 The solenoid valve block assembly cannot be serviced without removing the hydraulic brake booster assembly from the vehicle; the 1986 engine intake manifold is too close to the valve block.
Removal
1. Remove brake booster assembly from the vehicle as outlined on page 12-29-6.
2. Using a 13 mm hex socket, remove three nuts and washers holding the valve block to the master cylinder.
3. Slide valve block away from master cylinder until it clears the three mounting studs.
Installation
1. The mating surfaces of the valve block and master cylinder must be absolutely clean.
Figure 2:
2. Fit four new square cut O-rings, wetted with brake fluid only, in the four ports (Figure 2) of valve block mounting face.
3. Slide valve block into three mounting studs making sure O-rings remain in place.
4. Install three new washers and nuts. Tighten nuts to 21-29 N-m (15-21 ft.lbs.).
5. Install brake booster assembly as outlined on page 12-29-7.
6. Test the completed repairs as follows:
a. Clean area surrounding valve block at outlet ports and mating surface, making sure to remove all brake fluid.
b. Turn ignition on. Wait until brake light and anti-lock light go out.
c. Apply brake pedal with medium force and hold for 15-30 seconds and release. Repeat three times.
d. Check for leaks at valve block tube seats and mating surface.
Hydraulic Pump Motor Description - Page 12-29-3 The following supplements the Shop Manual pump motor description:
During the 1986 model year a thermal circuit breaker was added to the electric pump motor (approximately March, 1986). An overload, such as running continuously for 20 minutes or more can trip the breaker and shut off the motor. Before condemning the motor, let it cool down to allow the circuit breaker to reset. Reset time may range from two to ten minutes.

Removal
Due to the proximity of, the 1986 engine intake manifold, the hydraulic fluid reservoir must first be removed to provide clearance for removal.
1. Refer to hydraulic reservoir removal outlined in this TSB communication.
2. Proceed with instructions in the Shop Manual.
Installation
1. Install the pump assembly onto the retainer pin and swing pump outboard into position. Install the alien head bolt and thick spacer (spacer between rear shock mount and extension housing flange) and tighten to 7-10 N-m (5-7 ft.lbs.).
2. Install hydraulic fluid reservoir as outlined in this TSB communication.
