A couple of question's for all you mot testers

[Roverman]

What is the procedure for testing the electric hand brake on my S type Jag on the mot ?

What is the procedure for testing the brakes on my X type Jag with all wheel drive ?
 
My local mot garage as just the two normal brake test rollers (n/s & o/s)

Thanks vaux

If it's an all wheel drive and the roller brake tester isn't suitable for testing them . Then the tester will use a de accelerometer . around 15 mph hard on the brakes gives you a % reading
Same goes with hand brake. Of course may not be able to test this either
Using above method if EPB

[Karl]

Electronic hand brakes are tested exactly the same as manual park brakes in the Roller brake tester

[Roverman]

Cheers KarlB for the reply, but with the normal handbrake you can pull the lever up in stages to check the brake performance and when its fully on, it usually jumps out of the rollers, with the electric hand brake its either on or off, so are you saying you would put the rear wheels on the rollers start them turning and then apply the handbrake if it jumps off the rollers its ok ?
With the all wheel drive I can't see how you can use the rollers, as when the front wheels are on the rollers the rear wheels will drive you off the rollers ?
I have used the old tack a meter in my younger days didn't realise they were still in use, and depends on the room on the forecourt, as I thought the tester is not allowed to road test the car.

Never had these problems years ago when I was testing

Thanks vaux

the car should be doing approximately 20mph before you apply the brake using a decelerometer in a car or on a motorcycle (front brake on a damp road, ar*e clencher!) landrover propshaft park brake are also concern when doing them for me, not much meat on the uj to instantly lock up & stop 1 1/2 ton of rusting meccano kit!

[Karl]

Sorry should be worded firmly and gradually applied

If I couldn't be sure it was safe to use RBT for either park brake or service brake

Then it's the de accelerometer. I doubt the park brake can be tested this way either so it's a pass effectively

[Karl]

Allowed to use public highway to perform brake test. Easier /safer for me to use the car park though

Shouldn't be performed on a busy road

[Roverman]

Thanks for all the replies, I will do my normal pre mot check, with both cars up on stands and the handbrake on make sure the wheels are locked and I can't turn them, then the same with the foot brake, then road test to make sure they don't pull to one side.

I like to make sure my cars pass the mot first time  

The reason for my question's, its my first experience with the electric hand brake, can't see the point really, when you press the switch power goes to a motor which pulls the cables that work the calipers, must cost a lot more than the old lever the pulled the cables             Oh for the good old days     

Cheers vaux

if you mean the way i described the park brake application on  a landrover/propshaft park brake i guess you haven't done many, gradual application is how you do it, but not how the vehicle responds to it 

[Karl]

No it was an edit to my post 🙂

A car with 4 weeks mot remaining goes for its annual test, the only failure is emissions related, can the car be driven as is legally or,does,it have to be removed from the highway until fixed?

TIA

IIRC the rule is you can still be stopped and fined/prosecuted for the actual fault (bald tyres/dangerous rust/duff headlamps) but you've still got a valid MOT until the certificate runs out in 4 weeks. I think you'd have to be very unlucky to get a roadside emissions test.

[givusaclue]

you're driving the car knowing that it's "unroadworthy" & doesn't meet minimum standard requirements set by law, so if they wanted to be awkward they've got you.
makes a mockery of having it tested early though & should depend on the nature of the failure items, but i don't make the rules, dvsa do!

[Noberator]

Technically if you vehicle fails an MOT you can take your vehicle away if your MOT certificate is still valid.


Yes you could get be unlucky and get pulled on route and it would be up to the Officer to ascertain on a case by case basis whether the vehicle is unroadworthy or not depending on the failure sheet.

If you say one of either below going to have defect(s) fixed after an MOT or a pre-booked MOT appointment (any decent Plod would check)just to make sure your not trying to pull the wool.

The only exceptions are to drive to have the defects fixed or to a pre-booked MOT appointment.

Minimum standards of roadworthiness at all times is open to interpretation.

I doubt the cops would know it's just failed an mot. As I suspect there info would still show it as having an mot .
