Inappropriate repair or modification. 2.1.10. Brake servo units, master cylinder (hydraulic systems) Visual inspection of the components while the braking system is operated. (a) Defective or ineffective servo unit. (b) Master cylinder defective or leaking. (c) Master cylinder insecure. (d) Insufficient brake fluid. (e) Master cylinder reservoir cap missing. (f) Brake fluid warning light illuminated or defective. (g) Incorrect functioning of brake fluid level warning device.
Inappropriate repair or modification. (f) Missing data plate. (g) Data illegible or not in accordance with regulations 2/ Item Method 2/ Principal reasons for rejection
Inappropriate repair or modification. 2.1.2. Pedal condition and travel of the brake operating device Visual inspection of the components while the braking system is operated Note: Vehicles with power-assisted braking systems should be inspected with the engine switched off. (a) Excessive or insufficient reserve travel. (b) Brake control not releasing correctly. (c) Anti-slip provision on brake pedal missing, loose or worn smooth. (d)
Inappropriate repair or modification. 2.1.17. Load sensing valve Visual inspection of the components while the braking system is operated. (a) Defective linkage. (b) Linkage incorrectly adjusted. (c) Valve seized or inoperative. (d) Valve missing. (e)
Inappropriate repair or modification. 2.1.3. Vacuum pump or compressor and reservoirs Without the engine running, deplete pressure/vacuum until warning device operates. With the engine running, observe time required for vacuum or air pressure to achieve safe working value. Check that pressure relief valve is working. Visual inspection of the components at normal working pressure. (a) Insufficient pressure/vacuum to give assistance for at least two brake applications after the warning device has operated (or gauge shows an unsafe reading). (b) Time taken to build up air pressure/vacuum to safe working value not in accordance with the regulations. 2/ (c) Pressure relief valve not working. (d) Air leak causing a noticeable drop in pressure or audible air leaks.
Inappropriate repair or modification. 2.1.13. Brake linings and pads Visual inspection. (a) Lining or pad excessively worn. (b) Lining or pad contaminated (oil, grease etc.).
Inappropriate repair or modification. 2.1.16. Brake actuators (including spring brakes or hydraulic cylinders) Visual inspection of the components while the braking system is operated. (a) Actuator cracked or damaged. (b)
Inappropriate repair or modification. 7.3.4. Suspension joints Visual inspection with vehicle over a pit or on a hoist. Wheel play detectors may be used and are recommended for vehicles over 3.5 tonnes GVM. (a) Excessive wear in swivel pin and/or bushes or at suspension joints. (b) Dust cover missing or severely deteriorated.
Inappropriate repair or modification. 8.1.7. Transmission Visual inspection. (a) Loose or missing securing bolts. (b) Excessive wear in transmission shaft bearings. (c) Excessive wear in universal joints. (d)
Inappropriate repair or modification. 2.1.3. Power source/ reservoir Vacuum pump or compressor and reservoirs Visual inspection of the components at normal working pressure. Check time required for vacuum or air pressure to reach safe working value and function of warning device, multi-circuit protection valve and pressure relief valve. (a) Insufficient pressure/vacuum to give assistance for at least two brake applications after the warning device has operated (or gauge shows an unsafe reading). (b) Time taken to build up air pressure/vacuum to safe working value not in accordance with the regulations. 2/ (c) Multi-circuit protection valve or pressure relief valve not working. 1/ Inspection of these items may be omitted, if it has been carried out recently and by the same inspector during the given periodical inspection under another Rule annexed to this Agreement (e.g. Rule No. 1).
