MOT Thursday - Do I need my rear prop/shafts?

Morning all,

My rear diff is playing up so in the meantime I've dropped the rear prop, removed the shafts and secured the handbrake drum in place.

Do I need the removed parts for the MOT?

Thanks

Presumably with the diff lock engaged the transmission brake is working ok? Just be sure they know to test it on the front wheels not the rear wheels.... I know someone who has a Hippo and he's tested it a couple of times now as a 2WD he keeps breaking something the week before the MOT!

Yeah all works fine! Just wondering

If the MOT station is friendly and you explain theres a problem that needs sorting, then you might be lucky but if you get some stroppy bloke...

Should be friendly. Though I'll give em a ring n double check. I know a lot of hippos go through as 2wd but not sure on fenders.

So long as the brakes pass the numbers it should be OK. The drive train itself isn't part of the MOT, unless it's fitted and hanging off!!!

Your handbrake is going to be your main problem, hippo's handbrake works on the rear wheels, not a transmission brake on the rear prop shaft, so running without a rear prop shaft in that case wouldn't be a problem. You could try explaining the situation and accept an advisory, but if you get a tester who insists that the handbrake should work on the rear wheels then you're stuffed.

Yeah rang up, no go. If the handbrake doesnt hold the rear wheels, its a fail. Which seems odd as it holds the entire car...

So changed the MOT for later in the month, get the diff fixed and fitted and go again

Useful to know, I assume it must work on the wheels it is primarily designed for, rather than just the rear wheels.

As Citroens used to have handbrakes that activated the front wheel disc brakes, they had a few instances of cars rolling away on a hill after a spirited drive due to the disc cooling down and the handbrake not pulled on hard enough....LOL.

Well, I didn't know that. My old Citroen had front wheel handbrake ... sorry for the wrong answer.

Makes me wonder how the Citroen passed then .... Ah well, many years ago now ..

Yep! Tad annoying as I wanted my MOT done with and kept away from December.

I think your MOT place is wrong .... acc. to Gov. MOT Manual The only stipulation for rejection is that the handbrake must stop at least two wheels turning, it doesn't specify which axle. I'd guess your MOT place drives vehicles in and the brake test rollers are setup for rear axle only .... and they CBA to do anything to help ..

Hmmmmm I did think that was unusual. Was using the place Gigglepin (they couldnt see an issue) use as its pretty close and Defender friendly but the MOT man said no

It might also be a case that if the diff lock was inadvertently moved to the unlock position, there would be no effective parking brake at all. In your case the effectiveness of the handbrake is relying on the centre diff being locked too.
And in this case, the tester isn't looking at what's needed to make the vehicle go, but what's required to ensure that it remains stationary.

Very true. Ill have to keep that in mind myself till next week at least

Yep, I was the victim of that in 2001 when one rolled down a hill into the house. House was stronger than French car!
