kiloromeo Posted February 22, 2019 Share Posted February 22, 2019 Good evening gents, any help here would be appreciated...Building a 270S kit, and today filled and tried to bleed the brakes, but very quickly found a leak (see pic).Anyway tried tightening - no luck. Tried tightening some more - no luck. Had another go and decided that if I tighten further something is going to brake ! So of course it is friday afternoon and Derek and the factory are not available to pester about a solution. I've checked the manual and I appear to have the correct washer. Am I missing something here? Thanks in advance. Link to comment Share on other sites More sharing options...
ChrisC Posted February 22, 2019 Share Posted February 22, 2019 Without doubt that’s the wrong washer, if no one posts the correct washer I will at the weekend when under my car Link to comment Share on other sites More sharing options...
Jim 123 Posted February 22, 2019 Share Posted February 22, 2019 It looks to me that the braided hose washer and locknut assembly is quite "thick" and this may be stopping the threaded male end of the hose from fully seating in the T piece threaded aperture.

Wrightpayne Posted February 22, 2019 Share Posted February 22, 2019 Should be a copper washer at least!on my car the flexi hose going to the dedion is long enough on the threaded portion to bottom out in the brass T piece and create the seal.Ian Link to comment Share on other sites More sharing options...
Wrightpayne Posted February 22, 2019 Share Posted February 22, 2019 There seems to be a locknut on it too - I’d remove the washer and locknut and see if it bottoms out.Ian Link to comment Share on other sites More sharing options...
Jim 123 Posted February 22, 2019 Share Posted February 22, 2019 To mention if you have to rejig the connection. A layer of cling film over the reservoir cap opening with the cap refitted will help reduce loss of brake fluid whilst you work. Sequence as no doubt you know is to fix the braided hose into the T piece with the other end tightened afterwards. Link to comment Share on other sites More sharing options...
Mark w Posted February 22, 2019 Share Posted February 22, 2019 wrong washer , use a thin copper one Link to comment Share on other sites More sharing options...
7 wonders of the world Posted February 22, 2019 Share Posted February 22, 2019 As above certainly the wrong washer, before your go and rebleed consider replacing the rigid rear brake pipes with flexible ones.Still cant believe CC get away with selling a car with these rigid pipes on, and IVA dont pick up on it either ....... connected to a floating rear caliper !There is a reason flexible lines are mandatory on race cars now.....

mike150 Posted February 23, 2019 Share Posted February 23, 2019 As above.............I would think it should be a dowdy washer for hydraulic fittings or a copper washer. Also I'd recommend using braided brake lines to the calipers as the rigid copper pipes make removing the calipers a pain. I was going to take my calipers off during my winter long tinkering but couldn't be bothered when I saw the rigid pipes and if I did so would have to disconnect and re-bleed the system.

CtrMint Posted February 23, 2019 Share Posted February 23, 2019 Having recently built mine, I'm sure the correct washer was in the brake kit packet.Mine certainly doesn't look the same, seems nicely sealed too. Do you still have the packet the bracket lines came in? Link to comment Share on other sites More sharing options...
CtrMint Posted February 23, 2019 Share Posted February 23, 2019 Just had a read of the Ikea style assembly manual, it mentions there "Brake pipe washers and nuts are included with the hose". Hope that helps. Link to comment Share on other sites More sharing options...
kiloromeo Posted February 23, 2019 Author Share Posted February 23, 2019 Thanks for all the replies.The manual clearly shows a washer in the diagram, and the parts list says 2 are needed (item IK ,2 no)...Anyway I went looking for thin copper ones but could only find some at 2mm thick, the same thickness as the one in there!Jim, thanks for the cling film idea, the mess would have been a lot worse without it. And the sequence did have me puzzled for a while, but you were right of course.Ian, I did as you suggested and it bottomed out ok, so helped with the decision to omit the washer.The advice re flexible hoses is appreciated, and maybe a project for the future, but for simple me I need to tick the boxes at the moment. Agree with the sentiment though, could be so much better. So could the manual, but hey ho.CtrMint - the bag it came in just had a lock nut, no washer, so I added the one from the manual. Thanks for the photo of your install, it looks like you do not have a washer, and as it doesn't leak I thought it must be fine, so I removed mine!Have now re-bled and no leaks, so will check tomorrow, and also see if I have a pedal.

mic Posted February 23, 2019 Share Posted February 23, 2019 There should NOT be a washer there. It doesn't really require the locknut but SVA will probably say it does. Link to comment Share on other sites More sharing options...
Sim Posted February 23, 2019 Share Posted February 23, 2019 Doesn't that imply that you may have a washer problem at the other end as well then... Simon Link to comment Share on other sites More sharing options...
Ian Mackenzie Posted February 23, 2019 Share Posted February 23, 2019 What is in the manual and what is supplied would appear different!A copper washer would normally be used on machined surfaced and not cast...If the end of the flexi-brake pipe that goes into the union looks like this:Then no washer or locknut for me......

andydavy Posted February 24, 2019 Share Posted February 24, 2019 any ideas where to get the flexible brake pipes for rear calipers? Link to comment Share on other sites More sharing options...
Wrightpayne Posted February 24, 2019 Share Posted February 24, 2019 Caterham sell them but are slightly on the short side. I got mine as a kit of parts from Demon Tweeks many years ago - speak to Dave kimberly. Quite straight forward to make them up.Ian Link to comment Share on other sites More sharing options...
