Stewart Posted June 24, 2007 Share Posted June 24, 2007 When I apply my hand brake the vehicle rolls about half a foot. Is this a MOT failure? after its moved the hand brake holds the vehicle. Am I right in saying its time for a new diff? Thanks in advance Stewart Quote Link to comment Share on other sites More sharing options...
Muck Truck Posted June 24, 2007 Share Posted June 24, 2007 Could be a number of things really, or a comination of them all. Worn UJ's, worn half shafts, worn drive flanges or a worn diff, or just be normal. Dont think ive seen a defender/disco that doesnt roll a bit when you put the hand brake as it takes up the slack. Shouldnt think it would fail a MOT, cause the handbrake does work. Our 98 Disco thats only done 44k miles moves a bit when you apply the handbrake and come off the foot brake, not as much as my old defender tho Quote Link to comment Share on other sites More sharing options...
Litch Posted June 24, 2007 Share Posted June 24, 2007 Because the handbrake works on the transmission and not directly on the rear wheels, any slack in the transmission has to be taken up before the vehicle will hold but I have never come across a LR which does not have some kind of movement with the handbrake firmly applied. Having said that, how much is too much is tricky to determine without actually seeing the vehicle however my vehicle is well set up with no real wear in the transmission and it still rocks, it causes those who don't know & understand transmission handbrakes a surprise but my MOT tester is more than happy with it and the brake is extremely effective.

Les Henson Posted June 24, 2007 Share Posted June 24, 2007 Rolling forwards a few inches is common and ok. The tester would stop on an incline and apply the handbrake. If it holds the vehicle it will pass. Transmission backlash is acceptable as long as the handbrake holds the vehicle and doesn't have excessive travel. Les.

nige90 Posted June 24, 2007 Share Posted June 24, 2007 Mine also moves a fair way in taking up slack and passes without comment. There isn't any mention in the MOT manual Linky about it either. Quote Link to comment Share on other sites More sharing options...

Stewart Posted June 25, 2007 Author Share Posted June 25, 2007 Im also getting a big clunk when I let the clutch out. Is possible to adjust the diffs? Stewart Quote Link to comment Share on other sites More sharing options...
