A bit more digging, apparently they are Ford Grenada rear discs and they need machining down. http://www.disco3.co.uk/forum/sankey-trailer-brake-overhall-128542.html

Thanks, the thing that doesn’t seem to match up is the number of bolt holes in the disc. Your post says 4 whilst the picture and text of the manual says 5

I’ve recently come into possession of an expedition trailer built on a Mk3 FV2381 Reynolds Boughton (Sankey) Widetrack chassis. It needs new brake discs and although there is lots of vague information online about it using Ford brake components- including ‘Scorpio’ discs, I can’t find a definitive source that says whether these are front or rear discs or what model year. I’ve managed to get the correct pads through matching the Mintex part number MDB1287. Grateful if anyone has any good information they can post here to help me and others in future. I’ve already found the army AESP which is available here: https://assets.publishing.service.gov.uk/media/5a817566ed915d74e6232608/20160119-FOI2016_00155_Palmer_Annex_A_Final.pdf

The obvious answer is to leave it unplugged. Clearly you’ve got a permanent live feeding the alarm sounder- either due to a short or due to the missing ECU / 10AS unit

Thanks again all. Just to round this thread off: I purchased the handheld tacho as suggested. Very simple operation: just attach some of the supplied reflective tape to the crank pulley and shine the laser pointer at it. Initial idle speed was approx 700 which according to Western's photo above is too low for a Defender 200tdi (never knew there was a difference between Disco and Defender). Idle speed adjusted up using the thumb-wheel on the throttle cable as it enters the fuel injection pump to 790rpm and the EMS-3 needs to be calibrated at 14.7 pulses per revolution to read correctly.

The genuine discovery WSM I have quotes 720 +/- 20 rpm as the 200tdi idle speed?

Thanks both. I've set the pulses/rev to where it displays 700 at idle and have ordered one of those handheld tachos; will fine tune the pulses until it matches exactly when it arrives

Grateful is anyone knows about the output pulses from a 200tdi A127-45 alternator that can help me. I've installed a Madman EMS3 engine monitor, which can function as a tachometer. I have connected it to the W terminal on the alternator and it is reading but needs calibrating- there are calibration settings in the menu of the EMS3 but I need to know how many pulses per revolution to set in order to get the correct read out on the rev counter... Any ideas? Here's the manual for the device: https://www.madmandevelopments.com/wp-content/uploads/2021/03/EMS3-v1_04.pdf Thanks in advance knowledgeable people

Grateful if anyone could help with the part number for the rectangular gasket that goes between the engine block on a 200tdi defender engine and this mounting plate beneath the fuel lift pump: HRC1873 Is the gasket ERR1475?

MRC5016 is the correct rectangular buffer for your bonnet

Have you driven it any distance? The diff lock engages mechanically but quite often the light doesn’t illuminate until the wheels have turned a revolution or two.

Thanks everyone, I've found the very rusty original calipers from the 90 that are indeed 41.6mm. I was toying with the idea of rebuilding them as I enjoy that sort of thing but just doesn't make economic sense when you add up price of rebuild kits, paint, vented spacers, new bolts etc. I'll go for a pair of new SEB500460 and SEB500470 as suggested by Mossberg. They're listed as defender fitment, are the later wider piston diameter and are single feed. Will roll the dice on them having the same bolt spacing to attach to the hubs- I can't believe Land Rover would have varied these? Point taken though around thread pitch. Thanks all- I'll update the thread when I eventually get round to the swap

Many years ago I swapped the front axle on my 90 (originally 1987 2.5NA) for one off a Discovery 1 which was in much better condition and which had vented discs/calipers. The only installation difference I recall was that the Discovery calipers had two brake fluid input lines which meant I had to put a T-splitter on each side to double up the Defender's single brake line connections. Now, those front calipers could use a refresh/rebuild/replacement and I'm keen to return to the single brake line input system to eliminate the T-splitters which have always seemed like a bit of a bodge (even if they have worked fine for nearly 2 decades). I presume that I will need to install Defender vented calipers? Are the Defender caliper bolt patterns compatible with the Disco axle (and all other RR/Defender front axles for that matter?) ie will any vented front caliper from any of the three models fit? Thanks!

So you’re a relay of information to your mate?

Hi everyone Does anyone have the exploded parts diagram for the rear trim (window surrounds) for a puma 90? I'm specifically in need of the details of how they are attached. ta muchly (thanks Ralph...)
