Hydraulic Calipers

                                                                      Extreme Medium Duty Engineering

A-LINE’s line of medium duty calipers are engineered to be a lot more than just medium. We know the severe service that school buses, delivery vehicles and emergency vehicles demand from their hydraulic braking systems.

That’s why A-LINE uses premium grade 80,000 psi tensile strength ductile iron and application-specific pistons. Get the best of OE specs coupled with A-LINE engineering to meet your fleet’s most demanding hydraulic braking needs.

Four Features Engineered For a Better Caliper

Fleets with medium duty hydraulic braking systems know that calipers have to withstand extreme temperatures and pressures.

A-LINE spec every caliper to meet or exceed OE standards for elasticity, thermal elongation and durability.

Every caliper is cast with high tensile strength pearlite ductile iron that has an ultimate tensile strength of 80,000 psi. This specialized iron allows the caliper to withstand high heats without loss of shape in the bore that can cause piston hangup.

Every seal and boot set is made of high thermal resistant synthetic EPDM or silicone to maintain lubrication in high heat environments.

While each caliper is uniquely manufactured with aluminum, steel or phenolic resin pistons, A-LINE will provide customized pistons to meet the fleet’s individual load requirements.

Finally, every A-Line new medium duty hydraulic caliper comes with a two-year warranty against defects in parts and workmanship.

Medium-Duty Hydraulic Caliper Identification Guide

Identification In Five Easy Steps:

1. Identify the caliper by looking at the top of the caliper to determine its style.
 

2. Count the pistons:

Two = Akebono, Bendix, Bosch, Dayton
Four = Meritor

3. Measure the piston/bore:

Akebono, Bendix, Bluebird, Bosch, Dayton, Ford, Freightliner, GM, Hino, IHC, Isuzu, Meritor, Sterling, Thomas, TRW and any other brand names are the respective intellectual property of their repsective parent corporations and are used for reference purposes only.
