Rear brake lines.

Rear brake lines.

Postby Brendan [OP] » June 23rd 2021, 10:04pm

Need to do the rear brake lines on my 2000 RWD.

Can anyone advise me on the materials and tools required? Never done this sort of thing before.

Do I have to drop the gas tank to do this, I would rather not, besides its full.

Thank you

A simple search in g00gull using the addy here should help find threads for RR brake line / component help.

And I do not recall folks having to drop the tank for the brake lines.

Your LAPS should also be able to help w/ tools maybe.
But they are fun to own and you know you're gonna' muck up one of them...
- only to find out months later while doing 70...

since you will be bending your own lines best bet is to use a coat hanger to make a trial bend around the tank and buy small clamps to mount it. I recently did a similar thing but on the front frame. I used 3 coat hangers and duct tape to mock up my new lines then slowly bent my new lines.

I whole heartedly second this opinion. Nickel/Copper lines are significantly easier to work with in all respects. Well worth the few extra dollars

I hope this isn't too late to be of help. I recently did a successful job on all the brake lines on my 95 Astro. As has been suggested Ni-Cop is best. Too bad the factory didn't use it... I would have gladly paid the extra $20 or $30 in added material cost. I removed the old lines and tried hard to not bend them so they could be used as a pattern for the new ones. Then i bent the new tubing to match the old lines as closely as possibly. This isn't easy. You can bend larger radius curves with your hands and thumbs but it helps to have a good tubing bender for the tighter bends. I have an old model 394 made by Ridgid. it's a 1/4" but works ok for 3/16 too. a double flaring tool is also necessary. DON'T FORGET to put the correct fitting on before flaring the end. I've done it before and it did not feel good. I did not need to drop the fuel tank. I left the farthest rearward part of the tubing straight and then bent it to fit after it was installed. The tank would need to be dropped otherwise. I left the tubing a little long and had to cut and flare the end that goes into the rear hose while the tubing was in place. I will save time to take notes and take photos of the routing of the original tubing so you know where the new one belongs... especially the tubes up front.

I just recently rented( borrowed) the double flaring tool kit from my local auto parts store.
I was working on my 1970 GMC school bus chassis, where it is close to 30 feet, front to rear, for the hydraulic clutch line ...for a rear engine school bus chassis.
The new 25 foot spool of NiCop line, came with flares and fittings on both ends. It was are a dream to work with, compared to the original steel lines.
I also bought a short length to cut up and practice with, but the first two flares came out perfect; so no more practice was needed.

Cheap flaring tools don't do well. I also wound up borrowing one from a professional mechanic friend after returning a junk one I bought at the local LAPS.

If you find the tank to be in the way... the braces may only need to be loosened for wiggle room. Otherwise, it sounds like you'll likely be able to work around it.

Have fun.. good luck
