Brake Operation Check
NOTE: An assistant is required to make a thorough brake operation
check.
1. Apply brakes to 80 psi and hold. Check all air line fi ttings and air
chambers for leakage.
2. Apply and release brakes while observing operation of brake
adjusters on each axle. As brakes are applied and released, brake
adjusters should move in unison visually.
3. Investigate source and make corrections for any discrepancies
found in Steps 1 and 2.
!
4. Drive vehicle at low speeds in a safe area and make several brake
applications to verify safe operation and absence of pulling,
grabbing, or noise. If any of these are noted, investigate and repair
prior to releasing vehicle for service.
CAUTION: Never release a vehicle for service if any brake
discrepancy - no matter how minor - is evident.
Lubrication
When servicing brakes or replacing components, lubricate per guidelines listed in Lubrication Table below.
Lubricate the following components with grease specifi ed in table:
• One-piece Roller —lubricate shoe roller recess.
• Two-piece Roller—lubricate shoe roller I.D.
• Roller and anchor pin recesses of each shoe on ES & ED 150-4L models
Do Not Lubricate The Following:
• Cam head surface or related parts that contact cam head surface. For effi cient operation, the cam head surface must remain free of oil,
grease or other contaminants.
Note: When lubricating the camshaft bracket, lubricate until grease comes out at the brake adjuster end.
The seal is installed at this end with the air side in so that grease purges out.
CAUTION: Do not use moly-disulfi de loaded grease or oil because this may shorten service life.
Important: In no case should the lubrication interval exceed the published intervals in table below.
Component Lubrication Interval Type of Lubricant
Standard Every 50,000 miles or every 3 months Standard Chassis Grease
LMS-Low Lube Every 250,000 miles or once a year* Mobilith SHC-460 Synthetic
LMS-Lube Free None* Mobilith SHC-PM Synthetic
Table 4. Lubrication Intervals
Note: The Bendix LMS-Low Lube brake uses a special “button head” grease fi tting. This helps identify the system as an LMS Brake
Package and also indicates that system should be lubricated with a Bendix approved synthetic lubricant.
The Bendix LMS-Lube Free brake is lubricated at the factory with Mobilith SCH-PM synthetic grease and does not require lubrication at
service intervals. There is no grease fi tting on the LMS lube free components.
Brake Adjuster Lubrication: Pressure Iubricate according to manufacturer’s instructions.
