    Replacing a clutch brake is cheap in comparison to replacing a clutch. May need a clutch if it is a self adjusting type and it's at the end of it's service life. If it turns out that it's just a clutch brake use the type that uses screws, it easier to replace later.

    Thankfully I've never had to torch a 1 piece clutch brake out (I was smart and always tossed the 1 piece brake in the trash whenever I changed a clutch).

    You did do the Due Diligence before you committed to the truck?

    This should have popped up with a good mechanic looking at it. AND yes I would tell the dealer fix it or take the replacement cost off the total.

    Clutch brakes can fail for various reasons, but when adjusted and used properly should outlast the life of the clutch. So if it failed before the the clutch is wore out, I'd want to know why.

    2 most common failures I've seen are:
    Clutch dragging from broken torsion springs. You can often find small pieces in the bell housing. A new clutch brake won't fix that issue, it needs a new clutch. If it just started having the issue, the problem is usually intermittent, depending on where the broken pieces are, the clutch brake may work fine once time and not the next. If let go too long, it burns out the clutch brake.

    The 2nd most common reason they fail is the driver, if he/she pushes the clutch all the way down when shifting, it puts extra wear on the clutch brake. If that's the case, then a new clutch brake will fix it. You can also get this from running with way too much free play forcing the pedal down near the clutch brake just to get it released.

    It could also bee that it the linkage wasn't set right when a new clutch was installed. I've seen a lot of people put it together and if the clutch brake works, they're done. But if the pedal is too close to the floor, it doesn't take much wear before the pedal hits the floor and doesn't give enough pressure on the clutch brake.

    Yes you can cut them out, but I will never tell anyone to do so when I have no idea what his experience is. Plus, If the clutch brake is worn out there is a reason it's worn out.... in an earlier post it was mentioned that a clutch brake was replaced in a 2012 model truck! Why would a 2012 need a clutch brake? lol I'm just total oldskool on my ways I guess lol. Be safe out there.
