What tools do I need for a brake flex line replacement project

[RFP]

I'm probably search-challenged, but I'm having a hard time finding a comprehensive list of tools that I will need to replace all four flexible brake lines on my '87 factory turbo look coupe. Could someone help a brother with a specific roll-call of what I will need? I have the hoses (ATE) on the way from our host, other than that, I'm at square one.

Many thanks, and happy holidays to all!

A 14mm open end (or 9/16) and a 11 mm brake line wrench. Not sure what size the bleeders are on your car but a good small adjustable will work. Here's a link so you can see what a brake line wrench looks like.

Rob,

Determine the fitting size/s and use flare and box type wrenches. Avoid using open or adjustable wrenches as much as possible. Use heat as needed.

9/16 and 11/16 open end wrenches (14mm and 18mm in a pinch, but I found that 9/16 and 11/16 fit better).
11mm flare wrench.
Flat blade screwdriver.
19mm socket and wrench for lug nuts.
Jack and jack stands.
brake cleaner and rags.


That assumes that you do not remove the calipers. It's possible to do the work with them in place, but it's much harder to see what you're doing. If you are willing to remove the calipers, then they have 2 bolts each, 19mm socket (17mm socket? I think it's 19mm...) for the front and a 17 or 19mm box wrench for the back (and lots of swearing and busted knuckles and annoyance).

8mm socket or wrench for bleeder.

Remove the calipers for changing the lines? You must be joking...

buy yourself an 11mm flare nut wrench..
The metal lines that connect from the caliper to the rubber line, are likely slightly corroded..

From experience, you CAN use a normal 11mm crescent wrench, but a proper flare wrench will grip it with much more positivity, and virtually eliminate the chance of rounding it or stripping it.

If you do ruin the metal lines, then you will need to order replacements from your local Porsche dealer.. and they usually have to get them from Germany.... ask me how I know all this!!

I just did this job on the weekend...

Also, getting the spring clips off is fun... they retain the end of the rubber hose and stop is pulling through the mounting...Mine were corroded and gunky and took a LOT of persuading with a lever to get them off.

This article has all the info you should need.

Almost certain this is the size for the rear (Can't remember if front is larger).

If you can validate with an everyday 8mm wrench/socket, spring $20+ and buy a Snap On 8MM six point or $10 for a MAC six point box wrench.(Used on Ebay)

You should be fine with a Craftsman quality six point socket.

Just insurance.

Seems to me that if you have to ask maybe you should take it to a shop, I just did my 87 and 3 of the four lines were rusted to the steel line, which means the hose has to be turned to unscrew from the steel line rather than the swivel fitting. A pita and if you don't realize you quickly twist off the tip of the steel line, another big pita. It all depends on the condition of the fittings, if you encounter frozen fittings, take it to a shop. My 2 cents. BTW see Why to change rubber brake hoses.

If you're going to remove the lines, you might as well pull the calipers, replace the pads, check the rotors, clean the calipers up well, check the wheel bearings, etc and then of course flush everything.

I can say that I replaced the stock bleeders with speed bleeders, and they are 8mm all around (just worked on them a few weeks ago). I cannot say if speed bleeders are the same size as factory bleeders...

Fair enough. I may even have speed bleeders on my rears.

I tried maybe three different bleeding methods. Motive etc. When you finally get ALL the air out, it's wonderful. Like, "Oh, that's what they are talking about".

Many thanks to all who responded! I did this little project on my '77 decades ago... wasn't too hard. Now, thanks to you good Pelicans, I know what I need and I can have all my tools n' stuff together and make quick work of it.

Thanks again!!

Factory Turbo-look models, while having none of the "go" that the Turbos do, have the Turbo brake calipers, correct? If so, the OEM bleed nips have a 11mm hex. Who's yer daddy?!

You dudes forgot to tell him to get a lug wrench for the wheels. You're slipping...
