I used the search, not much came up. Especially looking for diagram where lines are so I know what I'm dealing with.

I assume it's break lines. My sister was borrowing it, and she said it got progressively worse. I tried tonight in driveway - no resistance pushing pedal to the floor. Low fluid warning is on.

Also my cousin has same car and garage confirms theirs needs it. They want $1000 for both brake and fuel lines. I'd like to save cash.

Thanks

I haven't replaced any hard lines in my Impala - I did two on my wife's Saturn because I boogered up one of the flare nuts when it was really stuck. There was a post here within the last two weeks about someone doing one of the front lines and routing it a different way.

The lines I would use are the Poly Armor - Advance carries them and I think most other places do as well. It is bendable by hand so you won't need any tools to bend it. You will want to make sure you get the proper line diameter and fittings which the auto parts store can help you with if you bring in a section of replacement line.

The only slightly troublesome thing is getting a brake flaring tool right away. I ended up going to O'Reilly's and getting the OTC 6502 tool which they were able to get the same day. I couldn't find squat locally for a tool that made bubble flares, which I am assuming the Impala uses but you may want to find out from someone else or pull a line off the car. Amazon, Tooltopia, or other online retailers will be cheaper if you can wait for to get it.

SK Tools makes some great flare nut wrenches at a reasonable price if you need to pick some up. The ones at the auto parts store are usually complete crap and will strip your fittings.

Thanks for the reply. I was researching this morning some more. Still couldn't find a diagram, but lots of other useful info.

At any rate I looked at my schedule and realized it's mission impossible, so I have to bite the bullet and get a shop to do it. Mad That and I got a better price.

For sure I would do the bubble / double flare method. The whole job doesn't look too hard in technical skill terms, but it's the time to do all the fishing & shaping. Plus all 1st time jobs take a lot longer.

- I saw that post, pics would definitely help.
- Canadian Tire has a flare wrench set, good enough.
- Poly Armor; thanks, I'll ask about it
- I think Dad has a flaring kit, if not shrug. doesn't matter now.

The impala uses bubble flares. I just did all 4 lines and hoses on an impala, took me about 4-5 hours. The bends running down the firewall can be tricky at times for the rear lines. Just take your time and don't get frustrated or give up. The fittings are M10x1.0 by 3/16 line. Just take the line off, try not to bend it up too much, and copy with the new line.

I would recommend taking 1 line off at a time. You can get little plastic caps that take the place of the fitting you just took off (they screw in), or just make one your self. Then bleed that line and move on to the next. That way you can just do one line at a time and if you get tired, you can pick it up later.

Where do the rear lines bolt in at the front?
I did the 2 short rear lines last week, I plan to do the rest up to the front but couldn't see how to get to the lines once they go up to the abs module?

Look at the anti sway bar area. What I did was take off the line at the ABS module, cap it and then pull it out of the holders, cut it at the bend under the car. I then made the same bends on the spool of wire, fished it up clipped it in and then ran the line back to near the fuel filter. It takes a couple tries to fish it in there. Try to use the factory mounting locations.

Also, check into the braided rubber lines. I've used them on many cars & they always help with pedal pressure/feel, plus they dont wear out like rubber lines. Been running them on my Dodge Ram beater for 100K so far & love them. Russell makes a direct bolt on kit for Impalas. Forget the price (60 bucks?) but well worth it. Check Summit & Amazon for the best prices. They replace all the rubber lines, front & rear. The same price or cheaper than stock replacements.
Here's my junk on the front of the Impala-

+1 Great point. It looks like the price has come down on braided lines a bit. I got the rubber lines on a close out at rockauto for 5 bucks a piece. The rubber lines are often neglected. If the outside rubber is cracked replace them.
