What are the repair procedures for hydraulic braking systems?
repair procedures for light vehicle hydraulic braking systems, including procedures for: removing, replacing and adjusting hydraulic system components, including master cylinder, proportioning valves, switches, brake hoses and lines, disc callipers and wheel cylinders
How does a diagonal split braking system work?
The second is called a diagonal split braking system. There are different reasons for both, though they share the common goal of straight-line braking. Since braking systems work based on hydraulic fluid that runs through lines that apply pressure to braking cylinders in the wheels, a brake line failure may prove catastrophic.
How many master cylinders does a split braking system use?
This applies to both systems. Sometimes, split braking systems use two master cylinders to control each conduit (brake line). This is akin to a double safety back-up.
What is a proportioning valve in a hydraulic brake system?
A proportioning valve may be used to reduce the pressure to the rear brakes under heavy braking. This limits the rear braking to reduce the chances of locking up the rear brakes, and greatly lessens the chances of a spin. The vacuum booster or vacuum servo is used in most modern hydraulic brake systems which contain four wheels.
Where does the split brake system come from?
The diagonal split concept comes from the fact that the left rear and right front brakes are on one hydraulic line while the right front and left rear brakes are on another.
What are the components of a hydraulic brake system?
These systems will consist of the straight bore master cylinder (1) actuated through an actuating mechanism (2) and the brakes (3), see Figure 2. Power Cylinders Through the years, larger brakes began to demand combinations of larger volumes and higher pressures than were capable from straight bore master cylinders.
What causes Cup to cut in hydraulic brake system?
If the brakes have a low volumetric requirement they will fill quickly and thus come to pressure quickly, often before the primary cup has passed the compensating port. This action causes the primary cup to be forced into the compensating port causing cup cutting as continued piston travel occurs.
This applies to both systems. Sometimes, split braking systems use two master cylinders to control each conduit (brake line). This is akin to a double safety back-up.
