    I had power brakes on the 55. They are still important even today if your brakes go out.

    Thanks for all the advice. I decided to move some things around & get it fixed before I leave, there's a local shop that I trust (as much as any shop) here in town that I had my alignment done at. They were worried about finding parts, but I lucked out & found a Cardone master/booster combo & already picked it up. Going in tomorrow.

    Well, it's another one of those limo-specific things. The 5-foot extension installed by the coach builder snapped. I need a custom cable made up. I bought some cable and random fittings as a temporary fix but haven't had time to mess with it.

    Back in the 80s I had a beater '76 CDV. Insurance was due to run out and I was putting a nice '77CDV back on the road and the car was going to be an engine donor. I used to slam into the dumpster at work every day on the way in. No brakes needed.

    I had to laugh at turbojimmy's description of his experience. Those truck ramps are filled with loose gravel and the vehicle that goes into one is supposed to sink into the gravel to stop it. It then has to be towed out of the trap by wreckers. I've used snow banks to stop some of my cars when needing emergency measures. A friend once used those old pillar type guard rails. They do a lot of damage to the car.

    When the brakes failed on my 87 Caprice (line broke before the prop valve), I used a Tercel to stop. I was going about 45, the Tercel was not. It wasn't pretty for the Tercel.

    Gee, if you were out here I would have a guy I know make you one. He is at a place called California Push Pull. He would be able to knock one out in about twenty minutes.

    A friend of mine stopped his Mustang with fifty feet of fence, a VW bug and ultimately a telephone pole when he dropped the linkage one time. He only got a cut on his arm doing all that. The VW lost its rear end.

    Done. My shop said it was a PITA to get it changed, but that did it pretty fast. I can tell a difference in braking already, they're more springy & responsive. (I still think the pedal could start grabbing higher, but I think ApeMan on here said that was a design flaw of sorts in '79?) Also, I didn't realize how bad my pedal return was until the new master cylinder & power booster... Now the pedal almost chases my foot back up, before there was a good delay, not enough to catch my attention, but it wasn't snappy. Glad to cross that off the list! I'll have to link back to this when I get the consolidated thread for my Phaeton started.

    I the same thing, it went on for some time but the brakes did fail, and fail BIG! I would fix this ASAP. No breaks in a Cadillac is literally a runaway train.

    I have blown the brake lines on my caddy and glad it happened at my ex-wife's house when it did, and not on the highway. The only brakes I had left was the e-brake and it was interesting loading the car onto the trailer to tow it to say the least.

    Get it fixed asap would be my recommendation
