Just been told to pass MOT need to replace Brake line. Passenger side is corroded.

I have 1989 f reg sport , standard so want some Brake lines to work with my car.

Which ones do i use? I have seen so many different ones and brands i not sure whether it makes sense to buy really expensive ones when the car will never do any track days etc

If you know where to get them from too that would be perfect.

Thanks

dealers will sell you pre-shaped fuel lines so they may provide pre-shaped brake lines also. I've never bought any before so not sure.

Firstly its always a good idea to give the lines a brush over before an MOT, then a wipe with an oily rag makes them look presentable for the tester. Of course they should be replaced if they are badly pitted, but surface corrosion and flakey paint sometimes make themlook worse than they are.

Not quite sure which ones you mean, the word corrosion would suggest the hard lines, but then you mention different brands which to me would say the flexi pipes. For the hard pipes you can get a good motor factor to make them up in kunifer a copper alloy, measure them with string and note the ends that are on them. Or you could buy yourself a roll of pipe fittings and a flaring tool, or as mentioned order the lines in steel from BMW.

For the flexi pipes, you cant go wrong with Goodridge, I think a whole set with stainless ends are about £65, you will need a 6 line kit.

HTH :D

Nope

dealer brake pipes are the right length but supplied straight so you have to bend them.

Thanks

I think first thing I need to do is actually find out exactly what he wants me to change and then I will have to work out where I go from there.

The problem isn't obtaining the replacement hard lines; it's fitting them. Brake pipes were one of the first things fitted to the shell at the factory and run above the fuel tank and rear beam.
