X Engineering Handbrake Conversion

Steve, I have witnessed 2 of these not holding, and not on real steep terrain, have heard from others with the same issue, I just don't trust them.
Never had the drum not hold unless not adjust correctly.

I always thought the main idea of going to the disc for a handbrake was for controlled braking when off road.

Discs don't have the mechanical advantage that drums have which is why 99% of cars with disc brakes on the road wheels require a brake booster.

yes coming to same conclusion, I thought it may be a better option (which it is but only for cleaning it) It just feels unsafe, I had the Defender rolling away from me in parking lot and me scrambling back in to prevent it from crashing in other cars. Have now tried many different adjustments but still nowhere near as good as drum

hm I think using disk for controlled breaking off-road would kill the break quickly, would think the force applied to single disk would rip it out if not careful not to mention manual says to never use while driving

I was looking at some conversion kits online last few weeks.
these mostly look like the common back hoe and industrial park brakes. often see these on light trucks/campers when they fit late model car gearboxes.

backhoe have one fitted to the rear axle and are for us are covered in mud etc. these require constant adjustment and checking. the adjustment is so easy that the handle twists-if its loose its obvious for experienced operators.

I expected the disc to be easily damaged, and have never had to replace pads. that wont be the same on a road going vehicle.

park brake is not suitable for as an emergency brake, most of these disc unit will overheat and glaze -even destroy disc. drum brake will suffer from being heavy, full of mud/water or the oil.

Im certain that there are owners here that will coat everything under the car with oil and rustproofing that the drum might keep out.
