2007 Dodge RAM 1500 Brake Service (ONLINE REPAIR MANUALS)

These self contained vacuum hydraulic power braking units are of the vacuum suspended type. They use engine intake manifold vacuum or a vacuum pump along with atmospheric pressure for their power, eliminating the need for a vacuum reservoir. A mechanically operated control valve, with integral vacuum power diaphragms, controls the degree of brake application or release depending on amount of foot pressure applied to...

Manual

• Remove reservoir filler caps and fill reservoir with proper brake fluid.
• If calipers or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws.
• Close each bleed screw as fluid starts to drip from them.
• Fill master cylinder reservoir once more before proceeding.
• Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially filled with brake fluid, Fig. . Ensure bleed hose is immersed in fluid.

Master Cylinder/Power Booster Test

• Start engine and inspect booster vacuum hose connections for leaks.
• Stop engine and shift transmission into neutral.
• Pump brake pedal until all vacuum reserve in booster is depleted.
• Press and hold brake pedal under light foot pressure. Pedal should hold firm. If it falls away master cylinder is faulty.
• Start engine and note pedal action. Pedal should fall away slightly under light foot pressure, then hold firm.
• If no pedal action is felt, the power booster, vacuum supply or vacuum check valve are faulty. Proceed to "Power Booster Vacuum Test."

These vehicles are equipped with dual piston calipers, sliding single piston systems, single non-metallic calipers, floating caliper-single piston or single piston caliper mounted disc brake systems.

Upon brake application, fluid pressure exerted against the caliper piston increases equally in all directions, creating the same pressure in the caliper bore and on the piston.
