Benton Posted April 7, 2020 Share Posted April 7, 2020 Whilst checking out the overall condition of the underside today came across two areas that require attention. The first was the missing powder coat/rust patches on both sides, I assume caused by road debris thrown up by the rear wheels. The second area, mirrored on both sides was the attachment of the handle brake cable. Is it meant to be attached in such a crude manner (the car was built by caterham btw)?Shouldn't the cable ties be at least wrapped around the rubber tubing thus holding the cable slightly away from the frame? The cable ties are so tight atm that I'm sure this is how it was assembled and the rubber hasn't slipped out. Link to comment Share on other sites More sharing options...
MADMALC Posted April 7, 2020 Share Posted April 7, 2020 That looks OK and how many do it. I used heater hose slit to cover the tube where needed so the metal cable was cushioned. The rubber on the cable is not always in the right place to use. Link to comment Share on other sites More sharing options...
Wrightpayne Posted April 7, 2020 Share Posted April 7, 2020 Or a bit of bicycle inner tube (lighter)! Link to comment Share on other sites More sharing options...
DJ. Posted April 7, 2020 Share Posted April 7, 2020 Crude but effective. Home builders have more time to improve small details like that (if they are so inclined). Link to comment Share on other sites More sharing options...
John Vine Posted April 7, 2020 Share Posted April 7, 2020 Yes, it's crude but it works. CC themselves recommend fixing it like this (from the IVA Checklist):That's how I've done mine, except that I used four cable ties rather than two (with that rubber sleeve as a cushion).JV Link to comment Share on other sites More sharing options...
DJ. Posted April 7, 2020 Share Posted April 7, 2020 But the extra cable ties are unnecessary extra weight Link to comment Share on other sites More sharing options...

Blue C7 Posted April 8, 2020 Share Posted April 8, 2020 Or use two sizes of stainless rubber lined p clips bolted together from car builder solutions Link to comment Share on other sites More sharing options...
elie boone Posted April 8, 2020 Share Posted April 8, 2020 If you talk about weight reduction, compare the original DD tube to the latest DD tubes. Link to comment Share on other sites More sharing options...
ChrisC Posted April 8, 2020 Share Posted April 8, 2020 It's a moving target how the factory builds them, they tend to tie wrap to the A-Frame and used the rubber to protect the chassis (not the A-frame) at the moment. I preferred the P-clips Link to comment Share on other sites More sharing options...
Drumster Posted April 8, 2020 Share Posted April 8, 2020 I've also used the '2 p-clip' method Link to comment Share on other sites More sharing options...
ChrisC Posted April 8, 2020 Share Posted April 8, 2020 Even still called "Hand Brake Cable Clip" on the Caterham parts websitehttps://caterhamparts.co.uk/fixings-other/365-clip-hand-brake-cable.html Link to comment Share on other sites More sharing options...
John Vine Posted April 8, 2020 Share Posted April 8, 2020 Post #5 here suggests that the IVA people might want to see P-clips.JV Link to comment Share on other sites More sharing options...
John Vine Posted April 8, 2020 Share Posted April 8, 2020 Re #5:I've just realised that that CC photo shows the cable attached to the A-frame. I'd be surprised if the IVA chaps would accept that, but I've no evidence either way.Just to be clear, my cable is tied to the chassis diagonal adjacent to the A-frame, and not to the A-frame itself.JV Link to comment Share on other sites More sharing options...
ChrisC Posted April 8, 2020 Share Posted April 8, 2020 I IVA'ed my 360 as per the 2016 recommendations, i.e. tie wrapped to the A-Frame, its also how I will present my 420R (when tests are resumed). For reference wording from the PBD, checklist as follows. "Check handbrake is routed correctly and secured to A-frame" and"Check handbrake cable is not contacting the driveshafts or brake hose when on the floor" Link to comment Share on other sites More sharing options...
Dixa1225 Posted April 8, 2020 Share Posted April 8, 2020 My car has just passed IVA , handbrake cables fixed to A frame using P clips . Link to comment Share on other sites More sharing options...
Benton Posted April 8, 2020 Author Share Posted April 8, 2020 So as we type I'm addressing the cable situation. Mine was cable tied to the A frame, having cut the ties the rubber hoses could have been positioned and cable tied as seen in the Iva illustration, so why they aren't who knows. I've got a couple of areas that now need repainting due to corrosion where the cable ties were attached. Gives me something to do though :-) Link to comment Share on other sites More sharing options...
7 wonders of the world Posted April 11, 2020 Share Posted April 11, 2020 It needs to be the A frame in order that the clearance between the cable and driveshaft is maintained thro the full suspension travel, you can get interference if the cable is secured to the chassis.
