ChrisC Posted October 11, 2021 Share Posted October 11, 2021 I use a mityvac to drain the fluid from the caliper / lines, it's almost drip free to use. Then just use the bungs that came with the original kit. Link to comment Share on other sites More sharing options...
aerobod - near CYYC Posted October 11, 2021 Share Posted October 11, 2021 Re #125, Mark, they should be the nylon "Race" washers, part number ZZ021463: https://caterhamparts.co.uk/fixings-other/1438-nylon-racing-washer-shim-175-x-32-x-1.html?search_query=+ZZ021463&results=1 Link to comment Share on other sites More sharing options...
Nigel B Posted October 12, 2021 Share Posted October 12, 2021 When I changed my LSD last year, I simply removed the callipers & cable tied them to the springs to keep them out of the way. I didn't disconnect the brake pipes from the callipers. There's sufficient flex in the pipes to be able to do this without putting a permanent bend in them. It was Peter Scott's suggestion (ScottR400D). He provided me with an invaluable step by step guide!Good luck! Link to comment Share on other sites More sharing options...
ScottR400D Posted October 12, 2021 Share Posted October 12, 2021 Hi Nigel! Mark is changing to flexible rear hoses so that's not much use to him! As an aside I bought 10 30x17x1 nylon washers for just over £2 on eBay. Relieve the hole slightly with a small scraper and they do the job of the race washers perfectly.

Nigel B Posted October 12, 2021 Share Posted October 12, 2021 Haha, oops! Read the whole thread Nigel! Thanks Peter, I was wondering why no one had suggested that. I swapped my brake lines for flexible hoses earlier this year. I guess there are pros & cons to that modification, but I think on balance it’s a good idea.

CtrMint Posted October 12, 2021 Author Share Posted October 12, 2021 Thanks all, appreciate the comments trying to save me time.I'm pulling the entire rear out, as I've also decided to upgrade the suspension too, so not just the brake lines.

CtrMint Posted October 12, 2021 Author Share Posted October 12, 2021 Drive shaft nuts, the ones which are handed should they be reused? There is no signs of abnormal wear etc, but they are a heavy version of a nyloc? So I'm wondering if they should be replaced. Thanks Link to comment Share on other sites More sharing options...
ScottR400D Posted October 12, 2021 Share Posted October 12, 2021 To be honest, at your car's age and mileage I'd have pulled the driveshafts with the nuts in place. Having said that, if you've removed them then I would say fit new ones. They're probably OK but they're a bit critical........ Link to comment Share on other sites More sharing options...
CtrMint Posted October 12, 2021 Author Share Posted October 12, 2021 think I missed that option. Pulling the ears off the dedion right? that would have allowed the drive shaft nuts to stay in place?Ahh well, will order them, £15 each isn't going to break the bank, and as you say they are a bit critical.

ScottR400D Posted October 12, 2021 Share Posted October 12, 2021 Yes, that's right. As long as you don't need the disc off and you can be sure the bearings.are OK it's a good method. But as you say, they're not too expensive. Link to comment Share on other sites More sharing options...
CtrMint Posted October 14, 2021 Author Share Posted October 14, 2021 I made some good progress this evening. The offside driveshaft is now out, along with the ear and the brake assembly which I removed from the dedion as one piece. The driveshaft looks unmarked and in good condition, as do the bearing on the ear. The one thing I can't figure out is how to disconnect the handbrake cable from the brake assembly. It's probably super simple, but I just couldn't unclip the rectangular eyelet from the hook on the brake. Could someone point me in the in right direction please.Thanks Link to comment Share on other sites More sharing options...
Dixa1225 Posted October 14, 2021 Share Posted October 14, 2021 Have you slacken the cables of fully? Link to comment Share on other sites More sharing options...
CtrMint Posted October 14, 2021 Author Share Posted October 14, 2021 yes, the brake assembly is free from the car itself, so I can move it towards the diff hanger releasing the tension etc. Link to comment Share on other sites More sharing options...
John Vine Posted October 15, 2021 Share Posted October 15, 2021 You'll need enough slack to pull the cable out of its housing on the caliper, then rotate the eyelet through 180 deg to free it from the clip.Normally, you'd do this by unwinding the big white knurled adjustment nut where the cable disappears into the tunnel.JV Link to comment Share on other sites More sharing options...
ScottR400D Posted October 15, 2021 Share Posted October 15, 2021 Still take a good pull on the eye of the cable as I remember it. Don't be afraid to lean on it. Link to comment Share on other sites More sharing options...
CtrMint Posted October 15, 2021 Author Share Posted October 15, 2021 hmm, I guess I'm being too light, probably a bit more force is needed.I Will be spending the entire day on it tomorrow, will give it another go.Thanks Link to comment Share on other sites More sharing options...
CtrMint Posted October 16, 2021 Author Share Posted October 16, 2021 Guys,I have the tunnel cover up, whats the best strategy for disconnecting the handbrake cableThanks Link to comment Share on other sites More sharing options...
ScottR400D Posted October 16, 2021 Share Posted October 16, 2021 IME the best strategy is to go under at the back, slacken the tensioner then just push the cable back from under there into the tunnel, to disengage from the diff bracket. No need to lift the tunnel. Link to comment Share on other sites More sharing options...
John Vine Posted October 16, 2021 Share Posted October 16, 2021 The simplest way is to remove the split pin and clevis pin (#2 here):Remember to cross the cable inner over when reassembling.JV Link to comment Share on other sites More sharing options...
CtrMint Posted October 16, 2021 Author Share Posted October 16, 2021 Thanks both, ended up pulling the pin and removing the entire assembly. I found the cable had a kink and damage to the plastic sheath. To prevent an potential balance issue, I've opted to replace the cable. As result the project has been delayed.

CtrMint Posted October 16, 2021 Author Share Posted October 16, 2021 Quick update.Old diff is out, drained and the back plate removed. I've then wiped the diff internals down for inspection, though I openly admit I'm not sure what I'm looking for in terms of faults. It certainly looks ok, i.e. nothing loose or broken. The oil had an interesting finish to it, certainly some traces of metal, but nothing significant. I've run a magnetic pick up tool through the oil and nothing notable. I also put a magnetic parts tray under the drain pan, again nothing amazing. I do admit I'm not really sure how the oil should really look.I'll upload a slide deck to Youtube rather than spam images to here. Would love to hear opinions.It wasn't all good news though. Removal of the shafts etc all went well, and once I committed to disassembling the handbrake assembly (thanks btw) I got the diff out with ease. Unfortunately I found a nasty kink in the handbrake cable and some heavy marring and compression on the plastic outer. Not ideal, so I've very reluctantly opted to stop, and source a replace cable. Very disappointing as I'd spent a long time preparing for this weekend, aim being to get the new diff in and the car built. I'm not sure why the damage occurred to the handbrake cable, I've never had any issues with it during use, and it was balanced during its Manx IVA. Bit of a head scratcher.

StevehS3 Posted October 16, 2021 Share Posted October 16, 2021 Interesting you mention a kink in the handbrake cable. I have a imbalance problem with the drivers side being stronger. I removed the tunnel cover and found a nasty looking kink in the inner cable close to the pulley area. I plan to replace the cable over winter but wondered how it came about - to avoid the same thing happening to the new one. Does your cable cross over just after the pulley (to stop it scraping on each side of the chassis)? Link to comment Share on other sites More sharing options...
CtrMint Posted October 16, 2021 Author Share Posted October 16, 2021 Hey, Yep it crosses over too. Your location sounds very similar too, sort of helpful to know it's not something isolated to my car and possibly something daft that I've done.

CtrMint Posted October 22, 2021 Author Share Posted October 22, 2021 CC parcel arrived this week. New handbrake cable and the 5 speed gearbox spacer. Not sure if I will be inclined to work on the 420R this weekend. I did tell myself to take my time over the process and enjoy it. It's pretty cool too, reminds me of my original build.
