C2 Front Brake Pipes

911-C2 · 2 Feb 2020

I have had a good search and must be doing something wrong as can not find much info on replacing the front fixed brake pipes. I would like to replace them with genuine Porsche pre made and at same time replace the flexis and hard lines to the calipers.

On the Internet I find mention of perhaps having to drop the subframe and the fuel tank but cant seem to find definitive info. Any help appreciated.

Front subframe needs dropping I think, fuel tank can stay iirc.

Check your steering rack hard lines too, they rot and only £40 for new ones.

Why put inferior steel lines back in? Bend some kunifer lines up, Will outlast you. Use black heatshrink on them before fitting if you don't like the look.

You might even get kunifer lines in without dropping the subframe. Steel you would have to bend which weakens it.

I've done the front brake pipes - the steering column needs disconnecting and the subframe needs dropping. The subframe supports the fuel tank. I did the rack pipes at the same time (company in Borsall Common makes them). Just put a jack under the tank - just run it down / empty.

I used OEM pipes - the old transverse pipe (left to right) goes under the off side tank strap and the new one goes over the strap.

The diddy metal pipes between the hose and calliper needed some quality mole grips to remove, as the fitting into the calliper corroded away to nothing.

You need a mate to help you dropping the subframe!!

Good luck.

While waxoiling the car I decided to change the last 3 exposed original metal pipes - 2 x nearside wing to block under the floor and the one which continues to the n/s rear. Bought OEM pipes in advance of stripping arch liners etc.

The bits I could see looked fine, however they were not!! Surprisingly it would appear the washer bottle overflow had cause sever corrosion!

Long pipes were a bit fiddly to weave in but not too bad. Rubber glove over the reservoir and cap back on stopped any leaks. The fittings into the ally block under the wing were a bit corroded so I cut the pipes and used a socket.

I went ahead and made up my own brake pipes and am very happy with the result. The only pipes I bought made up were the Flexi to caliper.

I have not replaced the Brake Pipe that goes from the connector block underneath the N/S sill to the O/S rear. I will probably have this replaced at a garage at a time the gearbox is out. The original pipe looks ok at present.

Out of the 8 Caliper bleed nipples, one undid with a 6 point 11mm Socket and T-Bar, 5 came out with a low powered impact gun, the last 2 needed a kettle of boiling water and the impact driver.

One nipple left its threads in the caliper and I had to run a tap through to clean it up, but now have 8 functioning bleed nipples.

I also removed the frunk carpet and inspected all brake lines under there which look like new.

Currently refitting all the plastic under trays now satisfied no leaks post test drive, lots of new clips and screws. I decided to paint the clips before fitting to make them last a bit longer.

A good job you've done there :thumb:

Good work. Can't take my eyes off that strut. Was it salvaged from the Titanic recently?

I replaced most of my brake lines over winter. I went with kunifer as couldn't think on any serious benefit to using the OE steel. Managed to get the front driver side one in without dropping the subframe on my C4. Not the neatest looking work and not quite the OE route was taken but it works and doesn't foul any moving parts. Making up the lines is quite a satisfying job.

I did drop front subframe, it was relatively easy on the C2. Only really had to swing the ARB down and drop subframe 20mm. Taking off the solid water pipes each side allowed me to use OE route and clips.

Rusty strut..... next years job all suspension. Cant get over cost of Bilstein B4 shocks for 911, feels like daylight robbery. Looking like £1k for shocks and springs so will be around £2k just in parts for full suspension refresh.

As for the shockers, I got a set of Bilstein B6 for around £750 from Demon Tweeks a few years ago, because of the cost they offered interest free credit which I took over 12 months, I didn't even notice the cost. I already had new springs fitted a couple of years before then so it worked out a cheap set up.

EDIT, just looked and the price has shot up significantly and they no longer do 0% interest credit, it's now around £1250 a set plus 15.9% interest

Shock cost is outrageous, no technical difference to any other car where a shock is £50.... bilstein B4 are about £700 a set. Do wish the M030 full kits were still affordable as I see reference to from a few years ago.

OMG £3k for the M030 kit at Porscheshop ! I paid £1250 18 months ago.

Have you tried the dealers? I have a VW Transporter and many OEM parts are significantly more expensive at 'specialists'!

This was the best I could find for M030 shocks only....

Great work on the brake pipes!

These prices make aftermarket shocks look good value. Konis?

I have Koni's on the transporter - a handling revelation!!

I paid £700 from the OPC for a full C4 Cab Tip M030 kit (shocks, springs and ARBs) to fit on my 996.2 Targa back in 2013. It was the most 'heavy duty' kit available, as there isn't one for the Targa. Mainly though...the price was a BARGAIN!!

I recently picked up 2x front, low mileage M030 shocks to replace the tired units on my 996.1 C4. Struggling to find rears, so may go Bilstein B4 for those and stick with the original M030 springs. Or perhaps go H&R springs all round. Many options, but all getting more expensive.
