W211 rear brakes ring spanner size

[dan1w]

Can anyone tell me what size(s) of ring spanner I need to remove the rear brake hoses? Obviously want to make sure I have everything I need before disconnecting anything.

Also, any other tips on this job would be appreciated, car failed the MOT on rusty brake pipes up in the wheel wells. I've changed pipes before but not on this car.

Cheers,

Dan

I can't say for certain, but usually brake lines are 10mm (possibly 11mm). - I would recommend one of those "crow feet" brake line spanners, they are the closest thing to a ring spanner that you can get on to a brake line (mine has a 10mm end and an 11mm end).

The flexible portion might be slightly larger (say 12mm), but that's not the bit that is corroded.

Thanks, I'm changing the hoses while I'm at it.

This might be of help if its the first time working on your W211 brakes.
