Brake Hose/Line: Testing and Inspection
INSPECT- Brake hoses at least twice a year for road hazard damage, cracks and chafing of outer cover and for leaks and blisters.
- A light and mirror may be needed for adequate inspection.
- If any of the above conditions are observed on a brake hose, it will be necessary to replace it.
CLEANING
If rubber deterioration is evident, disassemble all hydraulic parts and wash with alcohol. Dry parts with compressed air before re-assembly to keep alcohol out of the system. Replace all rubber parts in the system, including brake hoses, master cylinder rubber parts, and brake caliper and wheel cylinder boots and seals. Also replace the combination valve and brake pressure modulator valve, since they have rubber components inside which are not serviceable. Check for brake fluid on the pads. If excessive brake fluid is found, replace the pads. The system must be flushed if there is any doubt as to the condition of brake fluid in the system or if a fluid has been used which contains the slightest trace of petroleum or mineral oil based fluids.
