Bendix SB-6, SB-7 Service Manual

If you are working on a truck with Bendix air disc brakes and you don’t have the factory documentation, you are asking for trouble. I have seen too many guys guess on torque values or skip the adjuster check because they thought they knew better. That is how rotors warp and pads wear uneven. This manual—the Bendix SB-6, SB-7 Service Manual—is what you need on the bench. 36 pages of OEM spec data, exploded views, and sequential procedures that a first-year apprentice can follow without error.

Brake Testing and Troubleshooting – Page 14

Every air disc brake job should start with a proper test. Section 5 of the manual walks you through the troubleshooting procedure, adjuster check, and wear limits for both pads and rotor. You get specific wear check methods using guide pins for standard and long calipers—page 18 and 19 cover those. Ignoring these steps means you risk reinstalling a caliper that is already out of spec. Factory procedure is not optional here.

What Torque Values Are Specified on Page 9?

Torque requirements are listed in the General Information section. Bendix gives you the exact ft-lb values for caliper mounting bolts, carrier bolts, and brake chamber fasteners. No aftermarket guesswork. You need a torque wrench that reads in Imperial units, and you need to hit every number. On page 9, you also get lubrication specs and the list of required service tools. Do not substitute a different grease—it will affect adjuster function over time.

3 Safety Instructions You Must Follow

Section 4 is only one page but it will save you a hospital visit. It covers the mandatory safety instructions for service work on both axial and radial disc brakes. Includes proper spring brake cage procedures, lockout/tagout for air systems, and handling of compressed components. Read these before you break any bolts. I have seen a spring brake canister launch across a shop—that is not a drill.

Pad Replacement: Axial and Radial Procedures

Section 6 details pad removal and fitting for both brake types. You check tappet boot condition and caliper floatation before you even touch the pad retainers. The manual shows you exactly how to push the tappets back without damaging the adjuster—use the correct tool or risk internal thread damage. Pad fitting includes torque sequence for the retaining clips. Follow the order on page 23.

Exploded Views – Axial and Radial Components

Chapter 1 gives you full exploded views with callouts for every part. Axial disc brake components on page 4, radial on page 6. If you are ordering repair kits, the part numbers are listed right there. Section 1.2 and 1.4 break down repair kits and wear indicator kits separately. No need to cross-reference a third-party catalog. The image also shows the rotor orientation relative to the caliper carrier—get that wrong and you have clearance issues.

Diagnostic Equipment – ZB9031 and ZB9033

Bendix designed two diagnostic devices for these brakes: a hand-held unit (ZB9031) and a vehicle-mounted unit (ZB9033). The manual dedicates pages 21-22 to their operation. If you don’t have these tools, the troubleshooting section still works with manual measurements, but the diagnostic tools take the guesswork out of adjuster stroke and air gap checks. Worth the investment if you service these brakes regularly.

For ABS and traction control diagnostics on the same vehicles, look at the related Bendix EC-60 Service Manual – Factory ABS/ATC Diagnostics. If you need deeper info on older electronic brake systems, the Bendix Gen 4, Gen 5 Service Manual – Factory ABS Diagnostics for Trucks covers those. And for air compressor service, check the Bendix Tu-Flo 750 Service Manual.

Understanding how the brake interacts with the drivetrain is also covered in separate resources: see Manual Transmission for clutch and gearbox integration points, and Manual Transmission for gear ratio effects on braking torque.

Does this manual cover brake chamber removal?

Yes. Section 12 covers actuation cylinder replacement for both brake chambers and spring brakes, including removal and fitting procedures on pages 33-34.

What page lists the torque values for the caliper bolts?

Page 9.

Is this manual for both SB-6 and SB-7 models?

Yes, it covers both axial and radial disc brake versions for SB-6 and SB-7. The exploded views and procedures are split by type but all included.

Can I use this manual on a Bendix SB-8 or later model?

No. This manual is specific to SB-6 and SB-7. Using it on later models will give you wrong torque specs and component layouts. Stick to the OEM documentation for your exact model. The SB-8 and beyond use a different caliper design and adjuster mechanism. If you need those, look for the proper factory service manual. Aftermarket reprints often mix generics—don’t trust them.

Factory documentation is the only way to guarantee your work matches what the engineers intended. Stop guessing with aftermarket reprints that miss torque callouts or skip safety warnings. Access the Factory Manual from AutoRepairManuals and get the real specs for your Bendix SB-6 or SB-7 air disc brakes.
