is this a MoT failure or not?

Are rear brake discs with hairline cracks on the surface a MoT failure?

I'm sure they are, but more than that they're a bloody liability and I'd
be wanting to change them ASAP.

discs are greater than minimum thickness and more than 10mm on the pads.....
I don't mind replacing the discs, but would have to replace the pads as
well.... :-(

Yes, and?

For the sake of a few quid, are you really willing to drive around in a
dangerous vehicle?

If a tester's failed them, would you bet your life on him being wrong?

*If* they are only surface cracks, then the makers may say the discs can
be machined. On the other hand, machining will probably cost almost as
much as replacing them, and if the cracks turn out to be not just
surface crazing, you'll need new discs anyway.

If they're not hairline then the disc would no longer be disc shaped.

If you've got them hot enough to surface crack then you'll be wanting new
ones anyway.

I am amazed that someone would want to risk cracked brake disks. A set of
four drilled and grooved disks and 8x pads cost me less than £200. It
doesn't seem a lot to pay to able to stop a car.

Not me personally, but I know someone who had a track rod end so worn
that it dropped apart when turning. He pushed it back together and tied
string around it in a neat bow...

Oh, and a friend had a car with a wire spoked steering wheel. The spokes
came loose in the rim of the wheel, so when moving the wheel at low speed
he had to turn it by the spokes so the rim didn't fall off. The same car
had a failed front door lock, and would have flapped in the breeze, apart
from having a tow-rope tying the door pulls together.

Entry was gained from the rear doors, then by climbing over the front
seats, avoiding castration from the rope, and being careful not to use
the failing steering wheel for support.

Incredibly faulty steering box on an A60, I drove it round the North
Circular, it was impossible to be certain which lane it would remain in.
My father drove back a Transit several hundred miles with a steering box
that could turn right a bit and keep straight ahead, but not go left more
than a tiny, tiny amount. He was doing OK till a Police road block at an
accident, he then needed to do a 301 point turn to go back, the police were
heading toward him when he managed to get in the right direction and hared
off !

Several times towed back cars with failed brakes (single circuit in the 60s)
by using the failed car in front towing a car with good brakes, that felt
horrible as you have to absolutely trust the following driver.

A mk1 escort with an axle that could twist on the springs, after which it
would rub the prop shaft on the tunnel, you then had to snap the handbrake
on to move the axle back.

My Zephyr 6 with the jaguar 3.4 lump, the brakes would fade away completely
under one hard stop and the handling was decidedly dodgy, once I took
someone out for a demonstration run from the Chequers, at about a hundred
over noak hill it managed to leave the road, run up a bank and back onto the
road, my passenger did not even spill his pint, he was 'cool' without a
doubt.

My Cortina with 3litre V6, it was running on very old remoulds when (during
a burn with an XJ6) one lost all its tread and locked one back wheel at
about a hundred.

A mini that came in with all the front swivels worn out, it could go in any
direction it wanted, including up the verge, that was exciting, but I cold
not stop laughing, it was a bit like some game at a fair!

I've ridden a motorcycle that lost the engine earth wire when a rear
engine mount bolt came undone. The ignition was then earthed though
the clutch cable and lever. It was OK when moving as the clutch wasn't
needed. It wasn't so good when I had to stop and pull off again as
touching the clutch lever even with gloves made me part of the
ignition earth path.

Also ridden a bike home without a clutch cable. It had an electric
starter so was easy to pull off on.

1000 miles of high speed continental touring [1] with 6 spokes
missing/broken/lose in the back wheel. Week before going I had fitted
a new to me back wheel as the drum had cracked. Only to find the new
wheel fell apart 1/2 way though a 2000 mile tour. We were at the top
of the Susten Pass when a mate pointed out there was a spoke hanging
out the back wheel.

Had a CB125S pass an MOT with the horn disconnected. I think if I had
drawn chalk marks round the stand it would have still been sat on them
when I collected it. Clearly it was sound, I'd got it there, they had
heard it's exhaust and saw it could stop when I pulled up on the back
yard.

[1] CB500/F throttle to the stop all the way as I was with a Rickman
Enfield, Ducati 860GTS, Suziki GSX1000 and an Eddie Lawson rep Z1100.
They were all 2 up. Only after getting back did it transpire I was the
only one with anything that approximated a working speedo. The 2 big
Jap bikes had been disconnected, they were both "low milage". The
Rickman had a Smiths "handlebar ornament". At about 70-80mph the Duke
gave up on vaguely wobbling the needle over a 10mph speed range and
just flipped the needle round to "very fast".

I knew bugger all about the pitfalls of buying a cheap used car (I'd always
had bikes exclusively until then). I bought an old Beetle that was
effectively held together by its paint. I traced the wet carpets in the
front to a case of _no_ metal at all in the floor pans!! Just plywood
covered in underseal and carpet. Think 'Wacky Races' Anthill Mob!
I ran my old Marina 1800 estate into a raised roundabout (shit tyres and
lack of skill). Broke a track rod, but got the car off the road and borrowed
an old arc welder and did it by the road on an extension lead from a shop
nearby. Lasted until payday.
I swapped my old LR 109 for an ex-Police 3L Senator (old Monza shape).
Amazing fun car to drive and astounding exhaust note. Braking was always a
bit scary especially in the wet as it would pull sharply to the left. Had
tracking checked, and inspected all bushes/linkages etc. No joy. Eventually
traced it to very well hidden accident damage. The left front wheel was at
least 2" further back in the wheel arch than the right. The chassis 'leg'
extension was wrinkled for over a foot but covered in filler and underseal.
The inner wing had been cut out and a flat piece welded back in. Neat job
but Jesus!. I knowingly did about 10k miles in this motor until I could
afford to replace it.

A mate had the same thing in a Datsun Sunny, but on the passenger side
and the floor had dropped down a bit creating a forward facing under car
scoop. Hit a good puddle and a horizontal sheet of water would soak the
passenger. Bloody hilarious until he ran out of unsuspecting passengers.

20 ish years ago, Mk II Escort:

Arrived at a pub, 3-4 miles from home, and the brakes completely failed,
stopped the car with hand brake and dropping the gears. After calming
down, I drove the car back. The only sort of mitigating factor was that
I drove it like that late at night and there was much less traffic. But,
yeah, 3-4 miles with no brakes.

The fault, my brain aside, was a simple cylinder seal. Easy fix.

My first one was an old Vespa with broken throttle cable. I attached the
remaining part of the cable to the rear footbrake pedal. It was actually
quite good.

Towing a recovered shite old Cortina back from somewhere near Edinburgh
to S.Glasgow with no steering wheel - just a set of molegrips on the
splined shaft. We tossed for the Cortina - I won, I got to drive the
towing Landie.

A shite old Renault 16 with terminal rust on the right rear suspension
arms, easily welded up with some Dexion to get to Glastonbury and back
witha full load of camping gear and bodies (wouldn't dream of doing
that now).

My mate filled over some chassis rot on his Renault 10 with some Formica
plates, glued in place with Cataloy/Isopon. By feathering the edges and
painting it with schutz, it looked just like welded plating. Passed an
MoT like that. Crazy fucker.

There is a simple cheap fix, change the discs and keep the old pads.
In a few weeks the part worn old pads will fit the grooves in the new
discs perfectly.
