Default 93 Brake Pipe Line Problem

I was changing my brake hoses (short) and broke off the fitting on the metal pipe line. What a screw up! Well anyway, has anyone replaced the piping lines between the front brakes & the modulator behind the drives seat in the rear compartment? Do I have to replace all 5 pipes or can one be separated & replaced. Thanks for all help.

wow... I have never seen this happen... but as these age, and those ends corrode, I am betting it will become a bigger problem.

My suggestion would be to get some tubing, a compression fitting kit and just cut a little off and refit a new end. This would be much easier than replacing the entire line.

I would never use a compression fitting for a brake line. I would use a short piece of brake line with flared ends and then flare the end of the line that is still on the car and connect them with the proper fitting.

I take my 92 to a performance shop that handles a lot of SCCA cars. I had a kink in on of the lines and that is exactly what he did.

Good Luck

Why not use a compression fitting, we do it all the time in the semiconductor industry. This equipment operates at much higher pressures, and temperatures, along with corrosive gases. I doubt his brake system is going to see any problems. I would be more concerned with him trying to remove that line, and replace it, but, that's just
my .02$ worth.

If you're talking about the kind of compression fitting that uses a brass sleeve around the tube that gets squeezed onto the tube when you tighten the nut, this type of fitting won't tolerate very much vibration, and should never be use on a brake line!! You life depends on good brakes!! Use only "double flare" SAE approved fittings. These repair tools, and short lengths of brake line tubing (with the double flare ends already done) are available at any good auto parts store. Don't take a chance with cheap plumbing stuff!!

S.T.W!!

Compression fittings are not considered a safe repair for brake lines. I have seen them used but would never take the chance especialy since the correct double flared connection is only slightly more trouble to make.

This situation really sux! I am replacing the hoses and rear calipers on my car and ran into a stubborn fitting. It took almost a week of shooting it with PB Blaster (both threads and inside the barrel of the fitting), but it finally came loose with one easy tug. Me-thinks it was worth the wait.
