Rubber brake hose lines
Repalced my front disc calibers but can not seem to break the old rubber lines lose to replace with newer lines. The Rubber hose is attached to a metal brake line flange that has a metal clip on it. 1983 Golf diesel, It feels as if I will snape the metal brake line if I apply too much pressure. I can not find any information in my manaual on how to take it apart. Any help would be appreciated.

Re: Rubber brake hose lines
Old brake lines are a pain. Even using a line-wrench can round-out the fittings.
IIRC, the rubber section's end is captive and the line-nut should turn (still support the rubber line-end). If they look rusty further down the line, you might be doing yourself a favor by replacing them all. New lines rot-out much faster than the originals.
Brake hard-lines are usually so awkward to replace without the car up on a lift, that I let a pro shop do the work.

Re: Rubber brake hose lines
Can you tell me what size wrench I need to use on the hard line brake flange that attaches to the rubber hose?

Re: Rubber brake hose lines
May be 11mm for nut and 13/14mm for the flexi.
Varies somewhat:
Corrosion and distortion from previous removal all involved.
Vice grips may be the only way once correct spanner has started to slip.
Get tightest possible fit from 10m,11mm, 9/16th etc.
Cover new ones in wax, bitumen or paint....

Re: Rubber brake hose lines
Gently use a propane torch right at the joint. Gently.
Let the heat soak in...maybe several times. Gently attempt to rotate while still good and warm.
Done it many times and never was a problem.

Re: Rubber brake hose lines
Sometimes when you have a bolt in a nut,
you can squeeze the nut with vice grips to break the layer of rust so it will break free.
Same with the brake line connections.
Seems like I have to cut the little metal clip holding it all in place in the bracket.
Pull it away from the bracket and crimp down on the area the line nut screws into, on a couple sides.
It should unscrew easily.
