Transmission Fluid Hydraulics

You need to know how transmission fluid flows inside an automatic transmission.

Hydraulic Suspension Bushings

Hydraulic suspension bushings were developed in response to specific customer desires: quieter and better-handling vehicles.

Hydraulic Power Steering Service Opportunities

Hydraulic power steering is still the choice for some platforms and applications both new and old.

What DOT Really Means: Brake Hose Inspection And Replacement

Brake hoses are the most government-regulated components on a vehicle. Anyone making brake assemblies must be registered with the Department of Transportation (DOT). All aftermarket hose, fittings and complete hoses must conform to FMVSS 106 and SAE J1401. These tests are demanding and often exceed what a vehicle will see in the real world.

Take Time To Evaluate The Condition Of Brake Hydraulics

Mileage is an essential criterion for evaluating the condition of brake hydraulics. Keep in mind that, each time the brakes are applied, the master and wheel cylinder piston seals wear. Given time, the rubber cups in master cylinders wear to the point that they will not consistently seal hydraulic pressure. The result will often be a low brake pedal, poor stopping power or an intermittently sinking brake pedal.

Diagnosing And Repairing Worn Brake Hydraulics

During a service writer’s efforts to sell competitive brake services at the service desk, he or she often focuses on selling “good, better or best” brake friction replacements, while ignoring the added expense of repairing brake hydraulics. Unfortunately, neglected brake hydraulic systems can cause an expensive warranty comeback or, even worse, a serious traffic accident. In any case, it’s important to advise a potential customer of the importance of servicing and repairing worn brake hydraulics.

Tech Tip: Hydro-Boost Tips And Hints

Hydro-boost brake systems are self-bleeding if there is no other problem in the system. Use this initial bleeding procedure whenever replacing or servicing any component in a hydro-boost system. Normal driving conditions will remove air that remains trapped within the system when components are properly installed and there are no flow restrictions in the system. Always refer to the vehicle service manual for specific installation and testing procedures on import and domestic vehicles.

Tech Tip: Low Or Spongy Pedal After Routine Brake Service

Some vehicles may exhibit a low or spongy pedal after wheel end brake service that cannot be remedied by bleeding the brakes. This may be due to a prematurely deteriorated seal in the master cylinder. Remove snap ring and rearmost piston from master cylinder to inspect seals. If any deformation or deterioration of seals is present, replace the master cylinder.
