He showed me notes 20.4 recommended, looked like 19.45 actual. Similar on back but they passed MOT he said he gave me the benefit of the doubt for them on MOT.

He wouldn't let me have the sheet with measurements so I grabbed it and took a photo...it obviously went a bit weird then as they thought I diddnt trust them.

I would not trust them, after that. It is a judgement call, get some new discs and pads when you are ready, it passed the MOT, they just wanted some more work.

"Why are the brakes worn out? It was only serviced a month ago... Terrible bodging garage!"

The MOT is not some kind of high-point, it's an absolute bare minimum.

Sod "computer says". LOOK AT THE THINGS.When was the brake fluid last changed?

I'm sticking to the proper modern way of doing things , who cares when it was changed , the computer knows what to do and when

Because, of course, computers never get anything wrong.

Does the computer do any kind of testing of the fluid? Or does it simply add <x time> from when it was last told the fluid was changed, whether it actually was or not?

By all means, check the fluid with a hygrometer. Or just change it anyway, because that's probably not much more expensive.

I'm sure that the pilot of AF296 thought the same.

I dont think it was caused by worn disk brakes ! You dont need a computer to tell you not fly a large vessel into a tree at 30m altitude, its generally covered in pilots intro course, day 1 I think, along with get the wheels out before the tarmac comes

But the autopilot computer fitted to the aircraft (well, 7 computers in total) should have prevented the accident from occurring so in that particular instance, the computers didn't know "what to do and when".
The pilot tried to apply power and climb but the computer system didn't allow this to happen.

Any computer can go wrong (or be wrongly programmed) and I've changed enough aircraft computers for many different system to , realise that computers sometimes know what to do and when to do it but on many occasions this isn't the case.

Would I rely on a computer to tell me when my car's brake fluid needed changing?
No. The computer has no idea of my driving style, how often the cap has been off the fluid reservoir, how often it has been topped up etc.

It sounds bizzare, but the sensors that MAY have contributed to the crash were optional extras and were not fitted to this plane.

Plane crashes aside, take a wheel off have a look. Are they worn or not? Don't matter what computer or mechanic says if they are gone they are gone. If in doubt check it out.

Update...booked into a proper garage today, £30 not £25, and passed with not a single issue, not even the sidelight the computer says is out, definitely doesn't need two headlights and disks as we know now is highly subjective.

The first garage was Halfords auto centre
