The metal ends of the brake flexible hoses are called ferrules.

These can corrode quite well, and if the corrosion gets too much, it can restrict the internal diameter of the brake hose. This will not atop you applying the brakes - but can prevent the return of the brake fluid when you let go of the brake. this will cause binding and wear your brakes out more quickly.

Excessively corroded ferrules is an MOT fail - but excessive in MOT terms means REALLY bad.

How does external rust restrict the internal diameter of the brake hose?
 
It rusts on the inside of the ferrule as well as the outside - and so it crushes the rubber hose and restricts the internal diameter, and in severe cases blocks it.

Soz if I didn't make it very clear

Never seen it in 50 odd years, it would have to crush the adapter the pipe is located on. Have seen restricted flexis due to them breaking up or internally swelling to form a restriction but never being crushed at the adapter ends.

Rach the terminal ends on rubber brake hoses can get rusty but i have NEVER seen one fail because of rust. They would need to be virtually falling apart to be a problem. Someone is taking the **** if that is what they are on about.

Thanks Wammers, I'll probably leave them then. Spend my money on more fun!
 
Shouldn't requesting photos from Rachel of her pipe ends be done by private message?:eek::censored:
 
I've seen the flexi's break down & turn into one way valves completely locking the wheel.

Nevertheless, in the worst case scenario, for complete renewal you'd be hard pushed to get more than £500 to £600, unless they're doing the pads & disc's as well.
 
sorry rach just got back to this im kent to but its a big place im.happy to pop round n check your brakes pipes you supply the tea iv got a trolley jack n tools pm me
