Red winch front to rear brake calipper conversion kit disco 1/defender

[94Discovery]

I just upgraded my front calippers to the 110bigger calippers and vented disc and while searching i foud this :

You can install your front calippers in the rear 

Anyone installed this kit any input ?

thank you

Unless the plan is to fit the dual circuit RRC/Disco Calipers to make fiddle brakes I really don't see the point. You would have immense over-braking on the rear and would have to fit a a proportioning valve to weaken the pressure going back there and you'll end up at square 1 but a lot poorer!

What he ^^ said it's not difficult to lock the rear wheels in standard trim why would you need to make them better. Improve the front definitely but rear I would leave alone.

I have the original proportional,just a neebe question if i go bigger (in the process of installing them, including a newer master all flex hoses and rigid lines )in the front  and bigger in the rear shouldn't in theory be balanced instead of only bigger in the front ?

At this time i will leave them alone but you know it is a land rover where ever we can improve why not 😬😂

It isnt as simple as that, the better brakes up front the more weight will be transferred to the front, so you would actually need smaller brakes in the rear.

I can see a use for this if you always carry a very heavy load on the bed. But not for normal or competition use

I think it would be for highly specialist applications, and would be downright dangerous on most vehicles.  There must be a reasonable application for it, though, or it wouldn't be made - they could be opening themselves up to all sorts of liability if its marketed as a general upgrade.

So it's for a Series 109 to bolt discs on the rear salisbury, because a front disc conversion is more tricky to do... yeah, sounds like a recipe for just locking the rear wheels up and having an accident.

Can't wait to see the 1st accident investigation / insurance claim

its for fitting 4 pot calipers to the rear axle to allow fiddle breaks to actually work,

cant see any mention of fitting discs to the rear of a 109 apart from your comment

URL ends with "/109" I made the leap as it's a commonly done thing. Nowhere in the page does it say it's for fiddle brakes. Certainly that would be a valid reason for the kit, and probably a better idea than just bolting oversize callipers on the back because "bigger must be better".

[Snagger]

I wonder if the idea is to use the twin-line front calipers, like earlier RRs and Discoverys had, so that one line is connected to the pedal circuits and the second line to fiddle brakes, a hydraulic hand brake or some other secondary system so that only one piston pair operates under normal braking and the other pair under the "special braking conditions", whatever they are.

Sorry!  When I read that, I thought that maybe fiddle brakes needed bigger pads than the standard rear units to be able to have the braking capacity, rather than picking up on the twin line comment, and then forgot about it!  I've never tried fiddle brakes or even seen them up close, so only now get what you were saying. 

[Soren Frimodt]

Haha no worries Mate just saw more people mention the fiddlebrakes, and then you even mentioning the dual Circuit calipers and thought "hmm haven't I already said that?"  

[RedLineMike]

for using fiddle, you dont want the twin line calipers as that doesnt give enough grip on the disc, i used these brackets with normal single line 4 pots which worked excellent with the fiddles, however under really heavy breaking on tarmac even with the centre diff locked, it was still tail happy

end result was i took the calipers & fiddles off & went back to normal calipers

 

[Carloz]

Fitting rear calipers with bigger piston area makes the rear brakes lock up sooner and cause dangerous situations like going sideways on the moments you don't want to. Or even tipping over, ending up in the path of a lorry or whatever. => The same effect as with a failing brake pressure limiter.

Fiddle breaking can be done with the original rear calipers, the force needed depends on what diameter master cilinders and lever length you choose. Though you need to separate the hydraulic circuit on the moment you use fiddle braking. That solution must be incorporated in the fiddle master cilinders.

Easiest and most fail safe layout is to fit a separate set of rear calipers directly connected to their mastercilinders for fiddle braking.

Oh, first thought, great bought expensive LR brackets (for rear disc conversion) when I really wanted to add twin line calipers for fiddles but now I know that they don't work so no point!

Wow mixed emotions up, down, in the middle and back to happy all in one thread!
