It's always something............
 

when dealing with old cars! I put my 1980 SC up on jackstands to do an oil change and discovered that (apparently) the brake flex lines have swollen internally and are not allowing hydraulic pressure to the calipers to release! Sooooooo, I ordered a new set of flex lines from PP and will do the replacement when they arrive. Not sure why the old lines failed like this, they have only been on the car for about 20 years! I guess it's true, nothing lasts forever! On the bright side, I get two jobs out of one jacking!

It's common.

A friends car would pull violently to the left during on track braking.

Bled brakes, usual inspections etc, Everything's check out. Lines even looked good but internal swelling was suggested.
Swapped the line out and all was good again.

I would contact Porsche and ask for a warranty replacement. After all, they lasted only 20 years. :rolleyes::rolleyes::rolleyes:

Put a note on your calendar to replace those lines in 2040. Don't forget!

youre kiddin' us, right?

yes it is....

I'm sure Fred is joking......I hope Fred is joking.........:confused:

Kidding?
 

Nope, about 20 yrs should be just about right. I rebuilt a lot of the brake system when I first got the car and a few years later replaced the calipers with a new set I found on line. The good news is that after this repair it should be someone else's problem along about 2040!

We are so spoiled with these cars. 40 -50 year old cars that we still drive and even track regularly. Easy to get ANY part. Try that with anything British or Italian made.:D

One of my friends that is in the Ferrari club, but drives a 992 for his DD said the difference of the clubs is simple. The Porsche owners brag about how many miles they have on the cars. The Ferrari owners brag about how few miles they have on their cars.

With 175,000 miles on mine I still have 8 states to hit to get all the lower 48. New England is done, so it is just the big ones like Montana and North Dakota part of the country.

My brake lines lasted 36 years. Sounds like you got ripped off 😬

I had to replace the flex brake lines on both a 944 and 928 due to them restricting the release of fluid causing the brake to drag. and then on the 928 had to also replace the MC as it had some restriction in the rear line releasing pressure.

it was interesting that a guy who claims to be an automotive engineer, if I recall, went on an extended explanation of how this cannot happen.

wish I knew who he worked for so I could be sure to never buy one of their cars....:eek:

Fred I sent you a PM

Happened to me and my lines were only 40 years old!

My story is a little different, FWIW.

My car's original hoses were swollen after about 8 or 9 years. Car is '71 and had the problem in the late 70s and replaced with rubber.

Those replacements were still fine in 2005, but I replaced them just because they were old at that time.

Those new rubber hoses left a spongy feel. Not sure why.

Replaced them with stainless braided and have had a rock hard pedal since. YMMV:D
