barrett Posted November 20, 2021 Share Posted November 20, 2021 There was as of last week a Visa of some description in this yard I would assume it's a four-pot or diesel so possibly has the 'other' type of BMC with servo? Presumably there are other bits on it that could be useful for yours. Possibly worth a trip over, of find a helpful local shiter willing to strip bits off, as I think it's a bit of a trek from you?

That's not a bad call. I know some (all the later ones inc diesel?) have the BMC and servo on the passenger side and it's operated via a rod from the brake pedal and I don't think they would be suitable but I bet there's loads of other similar parts.

dean36014 Posted November 20, 2021 Share Posted November 20, 2021 That mounting bracket locks identical to the bolt pattern for a c15 servo. Might be worth having a look for one of those. I've a spare one you can borrow to try it for size if you like Link to comment Share on other sites More sharing options...

I was able to apply the brakes in my Dad's C15 from the passenger seat which he found hilarious * Saying that, it's only where the brake master/servo would be on a LHD C15 so perhaps it would all simply bolt in.

Servo brakes are probably a decent upgrade. Not that it's going very fast at the moment. We're all behind you though - keep up the shite work I'd have to find somewhere on the inlet manifold and drill/tap a hole. There's not much to the manifold though so maybe there won't be a suitable place. Link to comment Share on other sites More sharing options...

TU engines had two vacuum ports- one for the vacuum-controlled hot air mixer/emissions control; the other (circled) was a connection for the brake servo Looking at yours, might this be a good patch for a port to be welded/drilled+tapped in?

I did use PTFE tape on the threads for extra goodness. I can see your problem though as it's quite a dainty little thing on yours. Link to comment Share on other sites More sharing options...
MrSteve Posted November 20, 2021 Share Posted November 20, 2021 Why the desire to fit a brake servo- seems like overkill? You've got sporty twin piston calipers at the front already! Link to comment Share on other sites More sharing options...
Lankytim Posted November 20, 2021 Author Share Posted November 20, 2021 I've done a bit of part number googling and have come up with this site, they appear to have all the braking components I need to get everything ship-shape including the correct master cylinder, free delivery too! Has anyone had any experience with Onlinecarparts.co.uk? I think it's all based within the EU so I'm wondering if I'm going to get stung with import duty when it gets here. I'll have to wait a month or two to save up before I buy anything anyway. It looks promising though. Link to comment Share on other sites More sharing options...

Six-cylinder Posted November 20, 2021 Share Posted November 20, 2021 The brakes on my Twin Pot feel lovely without a servo, I would say they have more bit than my C15 with servo. Lankytim 1 Link to comment Share on other sites More sharing options...

Caliper seal kits are available after years of being unavailable here (if you want to stick with your existing calipers)- ebay or brakeparts.co.uk I use this cross ref site below to check part nos for all my cars. Here it it is for the rhd master cylinder: http://www.kakapart.com/oem/partscrossinterchange/citroen-95493193.html Jimblob and Lankytim 2 Link to comment Share on other sites More sharing options...
Jimblob Posted November 21, 2021 Share Posted November 21, 2021 As six cylinder says, the brakes are fine as standard. I've never felt they were lacking, it's such a light car.However replacing the brake pads did make a huge difference.

SiC Posted November 21, 2021 Share Posted November 21, 2021 Never driven a Visa but I quite like unassisted brakes. They feel different than assisted but you get more feel. I've been tempted to disconnect the servo on my MGB for that reason. It's also why the S1 Elise never had any servo assistance on its brakes.

Lankytim Posted November 22, 2021 Author Share Posted November 22, 2021 Another piece to the jigsaw! This 2cv fan has a smaller pulley which is needed to clear the hump on the electronic ignition module. There’s barely any difference compared to the Visa fan but it’s an essential item. It was very kindly sent for the cost of postage from a fella on the 2CV group on Facebook. What a nice bunch! The guy also has a broken LNA but it’s all the way over in France.

Lankytim Posted December 26, 2021 Author Share Posted December 26, 2021 After careful Christmas budgeting I've finally pulled the trigger on these brake parts from "onlinecarparts.co.uk" (soz kids, crap presents this year) The reviews are mixed with some reporting parts taking over a month to appear, incorrect parts being substituted for parts that are suddenly out of stock and a protracted returns procedure seemingly designed to discourage customers from returning faulty or incorrect parts.

somewhatfoolish Posted December 26, 2021 Share Posted December 26, 2021 On 11/14/2021 at 5:03 PM, Lankytim said: Interestingly the manifold seems to have a pinhole in the bottom which allows a certain amount of petrol to leak over the top of the engine should any fuel be poured directly into the carb. It’s like a self destruct mechanism should anyone dare abuse the engine in such a way. The engine gets covered with petrol and bursts into flame when you get a backfire through the inlet manifold. Not that it actually happened to me you understand… even I’m not that daft * Darkness interrupted play and as I’m at work for the next few days it’ll be later next week before I can have another fettle with it. I've always assumed the pinhole is crude means of dealing with the tendency of the float valve to stick and flood the carb; without the pinhole the manifold would fill up and drown the engine. With it a flooded engine can be left to drain for half an hour and then driven(at speed to keep the fuel under control) to somewhere the valve can be blown out or changed.

Manifold drains like this are not unusual on older cars, I can think of some other examples. The function is mainly to clear flooding due to over-use of the choke. They work alright and do not admit enough air to affect normal running, so nothing to worry about really. Link to comment Share on other sites More sharing options...

Lankytim Posted January 2, 2022 Author Share Posted January 2, 2022 There’s been absolutely zero update with the dispatch of these parts, only that they’ve received payment. Hopefully that’s nothing to be too worried about. In other news, I found this fuel pump that was liberated by me from some place I used to work at (I can’t think where). It works fine and should do as a replacement for the mechanical pump… unless anyone can think of a reason it won’t be suitable? Will it overfill the carb and spray fuel all over the place?

Six-cylinder Posted January 2, 2022 Share Posted January 2, 2022 Until recently I used a very similar looking Facet pump on my carburettor Range Rover. My guess is it will be perfect. LightBulbFun 1 Link to comment Share on other sites More sharing options...
