    That is not a design changed clutch brake. The one piece is still better but your right you have to pull trans back to replace with another one piece. What they used is a two piece clutch brake designed to be replaceable with out trans removal but they are not as good as the one piece. As far as the only two tab comment I suspect it was operator failure. Clutch brake is really only designed to be squeezed basically at low rpms when the clutch is disengaged. What screws them up is if the clutch pedal is pushed all the way to the floor at a high rpm it just overtorques it. If you double clutch are you pushing clutch all the way down instead of just enough to disengage clutch? I have seen this many times before were I used to wrench. My boss had highway tractors and did'nt hire the best operators alot of them were right out of driving school. I was constantly replacing clutch brakes. No offence to new drivers I believe it is the driving school fault for pushing double clutching and teaching the procedure wrong. And I agree with witchinghour hyd clutches are not a good design.

    I was told using engine brake when at low rpm's could mess up clutch.

    tabs breaking off is operator error. never clutch it to the floor while the trans is in gear and the truck is moving, that is how you sheer the tabs off.

    The clutch brake is designed to stop the input shaft when the truck is sitting still. Doesn't matter if there are 2 teeth or 10. If you try to engage the clutch brake while the truck is moving its going to #### #### up.

    That sounds like a hydraulic problem not a clutch brake problem. As previously stated the clutch brakes only job is to stop the input shaft while the truck is parked. If you push the pedal to the floor while the truck is rolling and in gear you are asking the clutch brake to stop the truck.

    Make sure when they replace the clutch brake, they don't torch it. A lot of techs will to save time. But that can ruin for front seal and the throwout bearing.

    That is called incompetent. They can also ruin the input shaft.

    Plus no seal in eaton/fuller or meritor. Mack had a seal. No torch on a mack trans. Use a torch to nip the outer ring and air hammer thru. Then if needed nip center with torch. Have to use a little smarts guys
