Extended brake line replacement, need some help.

Ok so I’ve taken apart and rebuilt engines and transmissions, but I’ve never done brake lines. I almost feel dumb asking for help but I’m somewhat afraid of messing this up. Does anyone have any videos or something I can reference to so I don’t crash and die lol.

It doesn’t seem too difficult, I have a 10mm flare nut wrench which should be the size? but I’d like a good step-by-step video?

 

I replaced my 4 lines, very easy job. Actually a hard job due to tight space but very easy in essence.
Check Y/T lots of videos.

 

If I only replace the rear, do I still have to bleed all 4?

 

I would bleed all 4. I have no experience with this specific job however.

 

I bled all four just in case, barely took any time. Theres a YT video of a fj cruiser I used for reference.

If you're somewhat mechanically inclined this is really a no-sweat install. I never have done brk lines in my life either and it was a cake walk.
Have things prepped. Tools in arms length. I took the spare out for more room. Towels or rags to catch the dripping fluid. GL

 

Always helping the community man. Thank you

 

I’ve done a few. You’ll want to bleed all 4 just in case. The tiniest air bubble will give you squishy pedal and reduced confidence in your brakes. There’s ways to bleed you brakes by yourself (with and without special tools/bleeder pumps) but it’s just plain easier with a second person. You’ll want to bleed from the furthest away from the master and work your way to the closest- rear passenger, rear driver, front passenger, front driver.

 

Also as a heads up, the rear brake lines are side specific and depending on where you buy your lines from the new set will have different fittings for their specific side. It’s a minor difference in the mounting flange, but you should see the difference immediately once you take a close look at the new lines. At quick glance they’ll look the same. IIRC, the “hexagon” fitting goes on the passenger side.
Also the top nut for the rear brake lines is a bitch and a half to get to so I’d start with those to get any potential frustrations out of the way early.
