Brake Line Advice

Recommended Posts

I am replacing the rear wheel cylinders on my 73 2002 and thought I would replace the original rear hard brake lines that run to my new stainless brake hoses. They are approximately 23 inches long, but I can only find 20in. and 30 in. lines with bubble flares at the local parts stores. The dealer wants $42 for this line. I was tempted to buy two 12 in. lines with a union but was advised to go with a single line. A bubble flaring tool runs around $22 at Amazon but some of the reviews talk about flaring problems. I am tempted to buy a 30 in, line to cut and try to flare it. Will the local auto repair shop bubble flare a line I bring them for a reasonable price? Need some expert forum advice.

I replaced all my brake lines using BMW OEM lines. Your dealer's price sounds awfully high. There is a listing of brake lines by length which I found more helpful than reference to the actual replacement part. The OEM lines are very easy to bend but I found it rather difficult to flare one of the ends. The lines have a plastic coating on them that made it hard for the flaring tool to grab--it kept slipping until the coating wore thru. Good luck.

I know we're spoiled here with very limited corrosion,

but are they really in bad shape? On a dual- system

car, I'm of the 'don't fix it unless it's got a problem' school.

Also, I've had poor luck with inexpensive bubble flaring tools.

that's what I got,

Thanks for the prompt replies here. I went to bleed my left rear wheel cylinder and the bleeder broke off in the cylinder. I then went to remove the brake line to replace the cylinder and the next thing I know I am twisting the brake line. So it's time for new cylinders and new hard lines. I will contact Blunt to see if he carries hard lines 24 inches long. Any other online sites that you would recommend? I would love to find bubble flared lines online at the correct length.

I did the same exact thing on my car. I didn't use a line wrench on the bleeder and broke it. I then used and open end wrench on the hard line that connects to the wheel cylinder and broke it right off. I stopped in my tracks and soaked the other side in wd40 and everything came off fine. You may be able to get away without the line wrench but the wd40 will be your best friend for this job.

If you want brake lines that are easy to flaire (flair?) and bend, use Cunifer.

Google it.

No amount of skill or education will ever replace dumb luck

Thanks for all the replies here on brake line lengths and availability. I have ordered two hard rear lines from Blunt.

On another note I just received my January Roundel. In Tech Talk Mike Miller is answering a 71 2002 owner's question about some basic repairs. The owner has the Haynes manual and Mike advises him to obtain the Big Blue Factory Manual. I keep reading thinking Mike is going to mention BMW 2002 FAQ as a site for "all things 2002". Not a word. This site is better than the factory manual. It's ALL here with friendly advice from a dedicated crowd of loyal owners.

This is what you want. Just give the part number you need, based on length to your BMW parts person.

I only use BMW brake pipes. Easy to bend. Should last another 40 years.

Who would you recommend buying these lines from?

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
