Hey guys, the rear brake line in my '93 reg cab 4x4 P/U corroded and developed a leak a few weeks ago. I guess at 190,000 Upstate NY miles something has to give...

My questions are: Is there just the one brake line that runs to the rear axle on the right side of the frame? Also, where can I find a new oem replacement without going through Toyota? Something cheap will be fine. Lastly, is replacing it pretty straight forward? My truck is rusty so it will be difficult I imagine. I'm at college right now away from it so I can't work on it any time soon, gonna have to wait a few weeks but that will give me time to get the brake line. Sorry for the newb questions, i'm not used to fixing vehicles since all we drive are Toyota's.


Also, it will be up for sale when it's fixed.

 

there is a supply line and a return line (that has to do with the load proprtioning sensing valve)

but instead of replaceing the entire line why not try to splice the "bad spot"

(or splice in a good 2' section or something....)

 

Oh yeah, and can someone show me where I can find an online parts fiche for this truck? Thanks!

 

What would I use at the connections to seal the lines together?

 

Same thing happened to my '88 a couple of years ago. It was right above the gas tank.

I bought both lines from the dealership, and if I remember correctly they were about $30 each. I figured that if one was that bad the other one probably wasn't too far from rusting through also.

 

Get some tubing, a hand bender, and some fittings and have fun!

 

got mine at autozone....measure the length and tell them it is for a Toyota.
about $2 a ft.

 

Thanks a lot guys! Does anyone know where there's an online parts fiche for my truck? That'd be helpful just to see how it's all laid out.

 

Splice into the line....it's much easier. Believe me...I've done it both ways. Get a tube flaring tool and appropriately sized flare nuts. It's all pretty cheap.

....I think!

 

I wouldn't trust my life to a splice into a rusted out brake line. Especially when you can get the factory lines from Toyota for $30 that are pre-bent to fit all the little nooks and crannies and have the correct fittings. Take your VIN number into the dealer when you order the new lines so they will match.

It is a PITA to get to those lines, you have to drop the gas tank or at least move it over some. Might as well replace the fuel line and fuel filter while you're at it.

 

I've had one for four years on my '86 and not a leak. A flared splice, if done right, is no different than the factory fittings. I did the work, so I know what I have and I trust it.
If it's rusted so bad that you have to cut away a sizable length of line, then sure...replace the whole thing. Soak everything with penetrate and have some flare nut wrenches.
In the end, you might even want to inspect the brake cylinders.

 

I did the rear brake lines from the Tee to the wheel cylinders on my 93 dlx pickup. My truck was also a resident of upstate NY when I got it two years ago and the brake lines were severely corroded (along with a lot of other stuff) so I just got factory tubes from Toyota. Having the right tubes, all pre bent, and with the flare wrenches it was easy. Except a couple of tube mounting bolts refused to budge, I ended up breaking them off, drilling and retapping them. Doing your own tubes with a bender and flaring tool to me is a good bit more work with a learning curve to go with it if you've never used them before. Either way, the job's going to be a "chore". Good Luck

Yeah, I only meant if it was one short length of tube that needed repair and not a whole section. When I repaired mine, only about 8 inches was bad. But, then my runner was never in NY.

 

Thanks guys, i'll look it over and hopefully i'll only need to take out a section instead of the entire line.
