At five years old my RAV doesn't have a great record at the MoT test centre. It failed it's first MoT because the headlamp aim was too high - i.e. from new and presumably as set by Mr T 'cos I had never touched it. No worries - they adjusted, retested and passed all within the single test session.
It passed it's second test - but both the MoT tester and Mr T at the most recent service noted that the front pads were wearing which is to be expected at around 50k miles.
Today I got MoT test certificate Refused; Fail; Do not drive until repaired (dangerous defects). It makes you feel quite bad! The report states that the front brake pads are now less than 1.5 mm thick but, at the moment at least, it stops perfectly well. So it's booked in to have the pads changed and a retest next week ...
... so to the question ... when I queried the wear last year I was told not to worry, just drive until the brake pad wear warning light comes on and get the pads changed promptly then. No warning light has ever come on. Does the RAV have such a system? Is the new MoT such that the criteria are more stringent than the warning system?

The mot tester at best can only give an estimated pad thinkness as it’s very difficult to see them in situ , ask to see the old pads once the job is done and querying it if the pads are more than 1.5mm 👍🏻

I asked to have headlights on the crv checked and sure enough one needed adjusting. That was on a car less than 12 months old! I don't know why it was out. The car had done 450 miles before I bought it but since then I have done nothing to cause it. It seems to be quite common on mot failures for all cars!

Back in January and at 47k miles, Mr T reported that they had 3mm left. If they start out at 12mm, that comes to around 5k miles per 1mm so I had been expecting to get another 10-15k miles before they needed changing - I wasn't aware of the 1.5mm figure as being part of the MoT test. I am now! And if they were around 3mm at 47k they'd certainly be down to around 2mm by 52k so I'm not about to quibble and I'm happy to replace them. But I was expecting some warning indication from the car that this needed doing - wrong again! The only "brake pad wear indicators" mentioned in the RAV handbook is "a squealing or scraping noise". Replacement pads are clearly marked as "Not prepared for wear indicator". So, waiting for the warning light to come on turned out to be a pretty dumb idea! Never to old to learn (though whether I'll remember is an entirely different matter)  |

Caused by low flying pigeons hitting the headlamps whilst the car is on a car transporter being driven from the factory. |

Headlight aim could probably be adjusted on the levelling switch. As for pad thickness, the rate of wear can increase as the material gets thinner because it forms less of a thermal barrier back to the backplate. However, it should have an audible indicator that causes a loud squeal at 2mm. I would ask them to keep the old pads so you can check this so called dangerous condition and if it is more than the claimed 1.5mm, tell them you want the pad change and the associated MOT doing for nothing to compensate you for the days lost work. That’s a very bold claim.

And I could never run fast! Thanks for the info Don ... that's what I was really asking about. So, it should have been perfectly reasonably and safe the drive until the brakes start to squeal and then look to having the pads changed? In practice, I'm perfectly happy to have the pads changed now rather than in six months time. And it's far more convenient to have a local garage and MoT centre do the work than drive all the way to the nearest Mr T. And I rather suspect that I'll get the retest for free anyway but I'll post back with the overall result ...  |

Well that's just 'tosh' ... not your post but the current regulations as written ... I've just checked the actual MoT Manual, section 1.1.13 Brake linings and pads (unlucky for some) and, assuming that the tester has measured correctly he is quite right: Brake lining or pad: - wear indicator illuminated
- Major
- worn below 1.5mm
- Dangerous
However, pragmatism ruled here - I still have a valid MoT (until 4th October); the car was perfectly safe to drive to the MoT test station, perfectly safe to drive home again and will be perfectly safe when I take it back in for new pads tomorrow. The garage certainly didn't quibble about my taking it away.
Maybe the tester was being over cautious and he could, and should, have passed it with an advisory. Maybe the 'squeal' indicator hasn't worked - I don't think that I would be deaf to it!. Maybe it would be better if Toyota fitted a brake wear warning lamp. Either way I'll take a look at the old pads once they've been replaced ...

This rule about the indicator being lit is just daft! plenty of vehicles don't have them. plenty of vehicles that do have them have them go bad (the VW T4s for example). The light doesn't come on on power-up and go off, so the tester has no idea if it has been bypassed/removed. and plenty of brake pads have the warning part set in a position so there is plenty of life left when it comes on (with a low mileage car could easily be over a year and definately ok untl the next service). What was wrong with just measuring the pad and leaving it at that?
What is next? MOT fail when there is a low fuel light on?
Ref driving away ... no problem with that as your MOT is still valid, but if you were stopped, it comes down to a test of roadworthiness - and if it stops it is is roadworthy on that count despite failing an MOT (another grey UK DLVA/DVSA contradiction).
(if it say failed on bald tyres and you drove away then that would fail roadworthiness of course - down to the owner deciding if it is ok to drive away or not)

The electronic wear indicators on BMWs will earn garages a fortune. They are a nightmare.

All sorted and MoT'd to October 2019 ... only a single test fee charged.
The pads probably didn't need doing just yet - on safety grounds at least. Measured pad thicknesses on the old pads varied from the best part of 3mm down to a tad less than 1mm on one of the inner edges so the MoT "less than 1.5mm" rule did apply.
I still don't know how the driver is supposed to know when the pads need changing without taking the wheels off to have a look. Perhaps the brakes would have started squealing within the next few thousand miles.
And, for the record, £84.00 to change the pads and £49.95 for the MoT ...

If you use the same garage regular and they know your rough mileage per year they can advise the pads won’t make it to the next service, or suggest you have them inspected in 6 months time .
We use to give the customer the choice ....more often than not they would have them replaced at that service being done save coming back 👍🏻
