I need to replace my passenger front metal brake line connecting the caliper to the flex line. Can someone tell me the size of hose that should be and the flare type?

I believe it's called 'bubble flare'. I picked up the the flare tool, and bought lines and a tube bender.

you want the 'Euro Metric' not just metric.

Cool thanks! I have a flare kit, but not bubble flare - I'll hit napa or something this week. The only one I could find OEM on the web was from AA for $25, compare that to a huge 60" brake line you can get for $5...

I did all 4 of mine last week. Turned out REAL well. (Haven't had it off the jacks yet, but it'll get there.)

Check my thread, there are pics and how I did it on there...

Here's a snippet:

QUOTE
Know your flares

There are four (more or less) flaring styles in common use for brake systems. British cars have a bubble flare (a.k.a. Girling flare) backed up with a male swivel nut or a 45 degree double flare backed up with a female swivel nut. Metric cars have ISO bubble flares, where the pipes and threads are metric sizes rather than inch. Detroit iron has a 45 degree double flare backed up by a male threaded nut. Most (non-British) race cars are plumbed with AN (a.k.a. JIC) type single flares - a 37 degree single flare with a backup sleeve and inch threaded swivel nut (some people make a double flare here, which is useless overkill and may lead to failure; see below). Lastly, some brake fittings use tapered pipe fittings.


Lots of flare info on the web.

Google search for "brake line flare"

LMAO.....buying the flare kit is OK if you do a lot of lines....but screw that....I just bought what I needed.

The left rear on Frank developed a leak at the top of the nut....too much flex from the umpteen times I took it off trying to re-index the godamned torsion bars.... (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)

AND

If your real careful...and patient...not a virtue "I" was born with....you can CAREFULLY do the bends by hand.....

I'm also changing out the fuel lines, and re-making ALL the brake lines. So I guess it wasn't TOO bad of a purchase. Besides...I'm a tool-whore.
