Professional Grade Wheel Cylinders

Raybestos® Professional Grade® Wheel Cylinders are a premium solution in the aftermarket industry.

Each wheel cylinder is built for a long service life and features the highest quality components, delivering top-of-the-line performance and safety.

Shortcuts are never taken when manufacturing our PG Wheel Cylinders. We match every detail to OE specifications, from the materials to the vehicle-specific designs. For example, where some competitors cut corners using soft wheel cylinder boots, our boots match OE form, fit and function.

Matching OE specifications ensures a performance that is:

  • Consistent
  • Safe
  • Reliable

We guarantee that our PG Wheel Cylinders will perform as good or better than the OE part.

Professional Grade Master Cylinders

Raybestos® Professional Grade® Master Cylinders give technicians a NEW part that fits each application as well as the original. Each master cylinder comes ready to bench bleed and install.  No assembly is required.

Here at Raybestos, we take pride in the fact that our master cylinders match OE fit, form and function.

Some of our competitors take shortcuts when manufacturing their master cylinders. For example, to cut costs, some competitors replace OE aluminum designs with cast iron. We always replicate the original aluminum design, ensuring a master cylinder that is:

  • Consistent
  • Safe
  • Reliable

We are confident in the components used in the construction of our master cylinders, and guarantee a performance that is as good as, or better than, the OE part.

Wheel Cylinders

Materials and Design

Our PG wheel cylinders have vehicle-specific designs and are made from either cast iron or aluminum materials.

Pressure Tested

Our wheel cylinders are 100 percent pressure tested, ensuring a dependable and leak-free performance.

Finish

A smooth bore finish delivers a high-quality seal. This increases the life of the rubber parts and ensures a leak-free performance.

Rubber Components

EPDM
and SBR rubber components offer superior resistance to:

  • Heat
  • Corrosion
  • Leakage

Bleeder Screws

The bleeder screws on our wheel cylinders are coated with a hardened zinc dichromate trivalent coating. This provides extra protection and added durability for a longer service life.

Master Cylinders

Materials and Design

Our PG Master Cylinders have vehicle-specific designs and are made from either cast iron or aluminum materials.

All New Parts

Each master cylinder comes ready to install with all new parts, including:

  • Castings
  • Pistons
  • Return Springs
  • Components

New pistons and return springs are vital to the performance of a car’s brake system, helping to prevent brake drag. Brake drag can cause the caliper and rotor to overheat, which will wear down your brake pads and rotor prematurely.

Pressure Tested

Our master cylinders are 100 percent pressure tested and meet SAE J1153 and J1154 requirements for reliability and performance.

Geometrically Tolerant

The master cylinder’s body and plastic reservoir match center to center for a:  

  • Proper fit
  • Leak-free operation

Bore Size and Finish

The master cylinder’s bore size and finish matches OE specifications, preventing fluid bypass, which can cause a loss of hydraulic pressure.

Rubber Components

EPDM
and SBR rubber components offer superior resistance to:

  • Heat
  • Corrosion
  • Leakage

Bleeder Screws

The bleeder screws on our master cylinders are coated with a hardened zinc dichromate trivalent coating. This provides extra protection and added durability for a longer service life.
