Well it's that time of year again, & yes nerves are thwart !! Is it because there may be expense involved ? Is it the thought of being without your baby? Or just the fact we are so sad & love them so much that it's like a visit to the dentist for ourselves !!!!
I do the maintenance myself so all should be well, but you never know ..

Comments Please

It's because there are so many muppets out there that don't understand that you cant put a 4wd drive car on a 2wd brake test rollers.

NS04

 

Thats very true. That and emmissions is all u have to fear.

 

Then you have the 18 year old YTS apprentice who must "road test" your car.

Yeah, cause I'm going to let that happen to my car!

Honestly!

 

Well I don't care one bit!!!

No, Pete, you didn't wind yourself up into a frenzy of worry about your car, did you?

 

Ever heard of tongue-in-cheek?

Pete

 

Of course. But you obviously missed mine

 

The MX5 goes in tomorrow ................

I have absolutely no problem except of an 18 year old taking the Impreza out for a brake test - in the end I drove .............. BUT, not before I watched them put it on the 2 wheel rollers!!! I ran in and stopped them before they did the rears!

They said that if the car doesn't spin-out of the rollers then its ok to test them that way ...... haven't had anyone mention anything about that on here, thought I would have?

Pete

 

i never have any problems cos my mate owns a garage and always mots my car.

 

Rubbish AFAIK!! You MUST NOT put a permanent 4wd car on 2wd brake rollers front or rear, it'll wind the centre diff up! It even says so in the MOT testers manual IIRC.

More muppets!

You're NOT suggesting that his eyesight goes a bit weird when your car rolls in ............ are you????

The tester just stood there and said to me, "Its ok mate, its not jumped out the rollers, so its ok"

I said he had better NOT put the rear wheels in the rollers .... he got the message after standing there facing me for what seemed like minutes but was probably a fraction of a second .... I was about to get my car outta there!!

Pete

 

no he checks everything properly but i haven't got the problem with young boys working at the garages wanting to drive it etc

 

Unbelieveable! You really shouldn't have to tell a so called 'mechanic' that the reason you don't put a 4wd car on the 2wd brake test rollers is because you could damage the centre diff. At that point I would have told him the test was over and that he would be reported to the DVLA.

NS04

 

Petes full of crap...

after his big boo hoo post,
he would have in triplicate and signed in blood, a deposition from the garage that the master enginers car couls not and should not be tested on the brake roller machine.

or..........

as we all thought, petes so full of crap he makes walter mitty look like a serial killer

pete lewsis the mouse!!!


LOL

So the subaru viscous center diff cannot cope with a roller brake test?
Is this fact?

Dipster

 

I would like to think that it would ........ and had I not been on this BBS then I wouldn't have known either way - my handbook talks about recovering the Impreza ONLY with a full lift

Nothing, I don't think? about a brake test which lasts for about 30 seconds

BUT, I didn't want any damage doing so insisted upon the road test (with me driving!)

Pete

 

Well Panic over, She passed & Guess, Yes they were going to put it on the rollers, But decided not to, when they struggled to turn the rear wheels whilst the rear was jacked up & Not the front.. & Me Standing there saying I don't think you should put it on there !!!!

Dean

 

mot never bothers me, mines well looked after so its never really a problem, although it would have failed the emissions test



if they had of actually stuck the probe up my shiney tailpipe

 

Did you let them take it out then?? ALONE!!

Pete

 

StickyMicky ..

I'm going to report you!!!!!

pete

 

for what?

you cant report sumbody for not having a diesel emissions test done on a petrol engine

 

if they had of actually stuck the probe up my shiney tailpipe [/QUOTE

Bit Muppety!

 

Dave as far as I know, the answer is: "it probably won't break the diff, but it doesn't do it any good!" The Subaru manual says you must not have the car towed on two wheels or you will damage the centre diff, I dont see that 2wd brake rollers would do anything to avoid this kind of damage. Since the 4wd is permanent I don't see any way around this!

Even the MOT testers manual says 4wd vehicles should be road tested IIRC.

Best,

NS04

 

Pete,
Definately No,
Does make you wonder how they treat them when your not there !!!!
Shudders with fear >>

Dean

 

Well, my 10 year old MX5 sailed through today

Pete

 

Great News,
How much extra Bhp do you get then for fitting Oars !!

Dean

 

Thats very SAIL mate!!

Pete

 

Thanks for the info,
I can understand that towing a scoob for a long time with one axle off the road would overheat a viscous diff, but a brake roller doing say 3mph for 10 seconds?
Am I looking at this the right way, in that if the diff does not overheat (like being towed as above) then no mechanical damage will occur during a brake test.
Surely the permanent 4WD note in the testers manual refers to diff locks on off road cars where the car would leap off the rollers and could injure workers.

Just an idea.
