DISC BRAKES, FORD MOTOR CO. -> General Information -> PROPORTIONING VALVE -> DESCRIPTION -> TESTING
Vehicle: 1990 Mercury Topaz 2.3 L4 GAS
DESCRIPTION
The proportioning valve (when used),Fig. , provides balanced braking action between front and rear brakes under a wide range of braking conditions. The valve regulates the hydraulic pressure applied to the rear wheel cylinders, thus limiting rear braking action when high pressures are required at the front brakes. In this manner, premature rear wheel skid is prevented.
TESTING
When a premature rear wheel slide is obtained on a brake application, it usually is an indication that the fluid pressure to the rear wheels is above the 50% reduction ratio for the rear line ...

HYDRAULIC BRAKES, FORD MOTOR CO. -> HYDRAULIC TUBING -> DOUBLE FLARE/INVERTED SEAT
Vehicle: 1990 Mercury Topaz 2.3 L4 GAS
Never use copper tubing as a replacement for steel tubing. Copper tubing is subject to fatigue cracking and corrosion which could result in brake system
Steel tubing is used to conduct hydraulic pressure to the brakes. All fittings, tubing and hose should be inspected for rusted, damaged or defective flared seats. The tubing is equipped with a double flare/inverted seat or I.S.O. flare to insure more positive seating in the fitting. To repair or reflare tubing, proceed as follows:
DOUBLE FLARE/INVERTED SEAT
- Using the tool shown inFig. or equivalent, cut off the damaged seat or da...

DISC BRAKES, FORD MOTOR CO. -> General Information -> BRAKE DISC SERVICE -> BLEEDING DISC BRAKES -> BRAKE ROUGHNESS
Vehicle: 1990 Mercury Topaz 2.3 L4 GAS
Servicing of disc brakes is extremely critical due to the close tolerances required in machining the brake disc to insure proper brake operation.
The maintenance of these close controls of the shape of the rubbing surfaces is necessary to prevent brake roughness. In addition, the surface finish must be non-directional and maintained at a micro inch finish. This close control of the rubbing surface finish is necessary to avoid pulls and erratic performance and promote long lining life and equal lining wear of both left and right brakes.
In light of the foregoing remarks, refinis...
