How do you adjust automatic slack adjusters Freightliner Chassis 36' motorhome Front brakes get hot and smoke while back brakes stay relatively cool?
the correct way to adjust automatic slack adjusters is to raise the wheel off the ground so it will spin. determine which slack adjuster you have,they vary from manufacture to manufacture, and get the appropriate tool. tighten the slack adjuster, the movement of the tool should be fairly smooth and easy if it is hard and clicks then you are going the wrong way. so tighten the slack until it stops and the brakes are in contact with the drum. make sure the wheel does not spin. now back the slack adjuster off, this is where it should be hard and clicking. back it off a quarter turn and see if the wheel spins freely with no drag. if it does not then back off the slack in small increments until the wheel spins freely with no drag. if you are having a problem with the brakes loosing adjustment then you need to have it inspected and find the root cause of the problem.this is for informational purposes only, i do not advise anyone who has not been trained in brake operation to perform this task, it should only be done by a ase certified mechanic. Do you have disc or drum brakes? Do they only get hot when you use them, or do they get hot when just driving?
What valves are anti-compounding valves?
Anti compounding valves are found in an air brake system on large commercial vehicles. These valves help to balance the pressure applied to the slack adjuster by simultaneously applying air to the spring brake relay when the service brake is pushed. The air is applied to the parking brake chamber as air pressure is applied to the service brake chamber thus releasing the parking brake the same amount that the service brake is applied thus "Balancing" the pressure in the brake chamber. This prevents excessive pressure from being applied to the service side and subsequently to the rod and slack adjuster. Thomas Moysey- owner A.B. CDL Training Center Waterford, CT
