BBB Posted January 14, 2022 Report Share Posted January 14, 2022 Last year was suspension refresh, 2022 is the year of brakes. I’m confident on the items for the discs, pads, sensors etc but it’s the following items that I could do with some help on. Is it worth changing the bleed nipples over to stainless items, if so does anyone have any links please. And do they go in with aluminium anti-seize when swapping? For the calliper hard pipes (not the ones underneath that link the two sides of the calliper) is it best to go OEM or do people make their own up? Mine are very rusty. I’m planning to fit braided flexi hoses, does it matter who makes them - Goodrich etc? Good source for these? I already have a GT3 master cylinder which arrived from Germany yesterday so that will go in the mix. Are there any modifications to the hard lines to the BMC required? The inlets seem to be M12 x 1.0 thread, is that the same as the original version so it’s an easy swap? I’m accumulating all the parts first, and then plan to fit all the items above in one go so I only have to bleed the system once. Any guidance appreciated.

entdgc Posted January 14, 2022 Report Share Posted January 14, 2022 Might be worth taking a look at the hard lines under the car as I have heard they can get quite corroded and are under covers so don't get spotted even at an MOT. 2 Quote Link to comment Share on other sites More sharing options...
½cwt Posted January 14, 2022 Report Share Posted January 14, 2022 Main thing with the bleep nipples is to use a flare spanner or 6 points deep socket to crack them off, avoids burring and decreases shearing risk too. Stainless as such won't gain you much here but avoid assembly compounds as it can contaminate the brake fluid, just some brake fluid on the threads does help though. Depending you your mileage and how far you want to go check for seized or sticky pistons in the calipers. For Brembo or after market spare parts for all of these, look up Bigg Red (among others), or go for full caliper refurbs with painting, seals, nipples etc. with the likes of BCS. For hard lines I'm planning DIY on my 986, I got the kit including tube cutter, flaring tool and fittings for about £80, but haven't been brave enough to tackle it yet, mainly due to when I started last time I found a broken front spring so all the suspension got done instead... 1 Quote Link to comment Share on other sites More sharing options...
Ninesomething Posted January 14, 2022 Report Share Posted January 14, 2022 If the brake fluid has been refreshed as per the service schedule the nipples should free off pretty easily. Clean and re fit. 1 Quote Link to comment Share on other sites More sharing options...
½cwt Posted January 14, 2022 Report Share Posted January 14, 2022 (edited) @JonSta no big deal, just need time and fine Spring weather to get on with it later this year... 🤞 Besides the suspension refresh has transformed the car, so a good thing, just a bit costly at £1300 ish in parts alone when all I wanted was shiny brake lines and fresh painted calipers that I'd bought the bits for already.

Ninesomething Posted January 14, 2022 Report Share Posted January 14, 2022 The crinkly face reaction earlier wasn't me. My dog added it while I was eating my dinner. I didn't know he could do that. Quote Link to comment Share on other sites More sharing options...

Very true, I am doing my brake lines at the moment and found that the brake lines under the car, which are covered by plastic under tray and toward the back of the car (passenger side-UK), were completely rotten. I was shocked how bad they were and they would never be picked up on MOT! As for the calliper cross pipes I just bought OEM because I struggled to get the correct radius on the bends - they are quite tight bends, but then that maybe due to my old equipment. Although they are expensive for what they are! I used a deep socket to get the old bleed nipples off making sure to apply even gentle pressure so as not to snap them. Replaced with stainless ones found on ebay. 2 Quote Link to comment Share on other sites More sharing options...
andy987 Posted January 14, 2022 Report Share Posted January 14, 2022 I’ve just had all of this done, went for cunifer lines, one issue was removing the hard lines that go into the back of the caliper, sent the whole to to BCS and they removed them. Bigger job than planned, aren’t they always 😂Will post some pics. Quote Link to comment Share on other sites More sharing options...
andy987 Posted January 14, 2022 Report Share Posted January 14, 2022 I cut one of the worst hard lines and although very pitted, MOT advisory etc the pipe wall still had a decent thickness of metal. Quote Link to comment Share on other sites More sharing options...
Ninesomething Posted January 14, 2022 Report Share Posted January 14, 2022 Why brake lines aren't all kunifer 10 is beyond me. I used to work in a motor factors and we made lines out of steel and K10. There was hardly any price difference. Mind you copper has increased in value since but still....

Correct, and easier for production as less easy to accidentally knock out of shape once formed during assembly. Quote Link to comment Share on other sites More sharing options...
