CORRECTIVE ACTION
6. BRAKES DO NOT HOLD - FRONT OR REAR DOLLY ONLY
Check brake fluid level.
Step 1.
Check level of brake fluid in the master cylinder (1). If level is
low, add fluid, bleed brakes (page 4-112), and check for leaks. If
fluid level is okay, go to step 2.
Check for restricted air lines.
Step 2.
Loosen line (2) at brake chamber (3). Apply brakes. If air escapes,
go on to step 3. If no air escapes, repair restricted line feeding
brake chamber (3). If problem is on the rear dolly, also check for
restricted interdolly hose (4).
Step 3. Check for bad master cylinder or brake chamber.
Slightly loosen master cylinder (1) to brake chamber (3) mounting
nuts. Gently apply brakes. If the units move apart it indicates that
the brake chamber is working. In this case, replace the master
cylinder (1) (page 4-116). If there is no movement in the units or
there is air leakage, replace the brake chamber (3) (page 4-120).
