Rigid brake pipes: excessively corroded
This one item accounted for 0.2% of every MOT test carried out in Great Britain, and it is among the commonest faults on 81 different model-and-year combinations. Here is where it clusters, and what it looks like on a car you are standing in front of.
How to spot it before you buy
On a clear, safe road brake firmly once from ~30 mph — feel for pulling or judder
Pulling to one side or a pulsing pedal means warped discs, a sticking caliper or uneven brakes (£150–500+).
The models it hits hardest
Ranked by how often the fault came up as a share of that model's own tests, not by raw count — a fault in 8% of a small model's tests says more about that model than one in 3% of the Fiesta's. A linked row has a page of its own.
