One more problem with my 4Runner. Last week, I was towing a trailer around the house. All the sudden the brake pedal goes all the way to the floor. I get out and look and see fluid dripping around where the gas tank is. Sure enough, the brake lines around the rear of the gas tank rusted out. What is my options. I've done a quick search for this and didn't find what I was looking for. Any thoughts would be greatly appreciated.

cheers
Sid

The lines can tend to rust out over time. This is what my lines ended up looking like around 15x,000:

Just get new line from the store and replace them. You'll need a pipe bender and cutter and possibly compression fittings. Not hard to do. Make sure you bleed in the correct order. My end result:

New lines run all the way back. good luck. <img src="/forums/images/graemlins/cheers.gif" alt="" />

Chances are you won't find metric brake lines, but you can find 3/16" brake lines with metric fittings that will work just fine. They come in 6" or 12" increments from a foot on up with fittings already flared on. If you need something other than the available lengths then you'll need the flaring tool.

The lines look great under the hood from the booster/cylinder. It was wet outside so I didn't look around the frame rail to see where the rust started. Is it best/necessary to replace the lines all the way back or can I start replacing further back. It just looks like a pain to bend/fit into the engine bay. Has anyone used other materials other than stock replacement such as rubber or stainless steel.

Cheers

i was very suprised at how cheap new lines from the dealer were for my 88' runner. the ones that run the length of the frame from the front manifold to the rear proportioning valve and the return. its been a few years but i think they were less than $50 for the set...might be worth a shot. the hardest part was getting them home without bending them. i also ran all new from the master cylinder to the fronts and that manifold on the pass side frame once i saw how good the others looked...
