Guest no1birdman Posted November 26, 2011 Share Posted November 26, 2011 Hi, I have put a few years ago the 3rd engine in, this one a 1600 diesel, now in all that time never really thought the brakes were that good, now if and when i put a 1800 diesel in the car will stop worse, now is there any good conversions ie off other cars that will stop it better, running standard brakes but sevo off a pump on diesel not manifold.I am 63 so nothing to complicated as it does not sink in to quick,had the car for 20 odd years , Thank you Quote Link to comment Share on other sites More sharing options...
Guest Lee81 Posted November 26, 2011 Share Posted November 26, 2011 2wd cosworth calipers and discs. Discs are 283mm so you will need 16 inch or bigger wheels to fit over them. They will bolt straight on. The only part you need is a 5mm washer to space the caliper out in line with the disc. its a couple of hours work if you've had some experience with car repair Quote Link to comment Share on other sites More sharing options...
Guest no1birdman Posted November 26, 2011 Share Posted November 26, 2011 Hi, do u fit them at the front and leave normal brakes on back, then buy some 16in wheels, running14in at the moment Quote Link to comment Share on other sites More sharing options...
Guest Lee81 Posted November 26, 2011 Share Posted November 26, 2011 Yeah thats what most do. You can fit the rear discs as well but thats not as simple plus you need a bias valve. But in order to do this the brake circuits will have to be renewed so alot of brake pipe work Quote Link to comment Share on other sites More sharing options...
Guest no1birdman Posted November 27, 2011 Share Posted November 27, 2011 Hi, so can u get thease cosworth disks from scrapyards or ebay, are they hard to find as never seen a cosworth in srapyard, once run car with 15in alloys off a mondeo but they caught bodywork. Had to put spring assistors on to higher body, thats why run 14in or is there a easy way, do not mind cutting bodywork as i can weld and spray, Quote Link to comment Share on other sites More sharing options...
Guest Lee81 Posted November 27, 2011 Share Posted November 27, 2011 Buy the discs and pads new as old discs and pads are never going to be very good. The calipers can be bought new from burtons or they come up on ebay alot for around £60 depending on condition. You shouldn't have any catchment problems on a 15 or 16 inch wheel unless your using the wrong profile or width tires on them. On a 16 inch wheel you should have a 45 profile tire in a width such as 185 or 195 Quote Link to comment Share on other sites More sharing options...
Guest no1birdman Posted November 27, 2011 Share Posted November 27, 2011 hi, thanks, i had big tyres on before,Will this make a real noticable difference in stopping Quote Link to comment Share on other sites More sharing options...
Guest Lee81 Posted November 27, 2011 Share Posted November 27, 2011 (edited) Yes as the standard setup is just poor even when new. I run the full cosworth setup on mine with tarox discs and pads all round. My car runs 368bhp and this setup is more than good enough for fast road use.

iansoutham Posted March 15, 2012 Share Posted March 15, 2012 Okay, my 2 pence on this one. Your car, as you correctly says, runs on a vacuum pump on the end of the engine cylinder head. The pump is operated by a cam with a pushrod. This pushrod does wear down over time, causing a lack of vacuum pressure within the pump. So, firstly, I would check the pump vacuum level to make sure it is getting pressure. Second, if the pump is working to full effect, then I would look at upgrading the front discs and pads to 260mm and calipers. On this engine, this spec on the front will be more than enough. The calipers can be found on most Sierra models with ABS, including V6, and all Granada models from 1985 onwards utilising either ABS or V6 engines. Discs can be sourced from either a 1986 onwards RS Turbo Escort or Sierra 2WD with ABS. These will fit behind the standard 14" wheels as well. On the rear, fit the larger rear drums if not already done (small ones have a built-in hub and drum, larger ones have a screw separating both pieces). Fit a MK3 rear wheel cylinder with an internal bore of 19mm. If you really want to add some pressure to the brakes, also fit the 24mm master cylinder assembly. I used to run an 1800 diesel Orion with 7" by 15" Cosworth alloys and Pirelli Drago tyres and I could lock the front wheels up with not a lot of bother if I stood on the brakes hard enough, all with the above setup.

Guest no1birdman Posted March 17, 2012 Share Posted March 17, 2012 thanks, so i just need 260mm disks and calipers not 283, do thease just bolt on with no spacers and just put my 14in wheels on. Quote Link to comment Share on other sites More sharing options...
iansoutham Posted March 17, 2012 Share Posted March 17, 2012 Yes, as long as the calipers and brackets (the bit the pads sit in) are for 260mm discs, then it is a simple bolt-together job. I have exactly the same parts on my cab ATM. Going for 283mm discs, you have to go for 15" wheels and sometimes the clearance can be a little close. On one of my other cars, I run 283mm discs and I have to be careful where I put any balancing weights as they are so close to the caliper, they can touch slightly. That is obviously a bad thing. The other thing with the 283mm conversion is that, if you run the Hi-Spec adapter kit (around £50 from Hi-Spec in Dartford, Kent), you still use the 260mm calipers and pads, but 283mm discs, but you need to shave a small section of the caliper carrier bracket back to allow clearance for the discs as they will expand slightly when they get hot (about 2-3mm in my experience), and you will need to tap out the lower hub mounting hole to take an M12 bolt. If using 4wd Cosworth and Scorpio 24V calipers, you bolt it together as per the 260mm caliper, but you need a 1mm washer on each bolt for spacing to centralise, you need the more expensive Cosworth pads as they are slightly larger in diameter and there are early and later calipers, M10 bolt fixing and M12 bolt fixing. They changed in 1992 and are not compatible with each other. In my experience, the 283mm conversion is better in the dry to a degree, but can be a nightmare in the wet as you can simply lock the front wheels up with ease if you are not careful, and that is with decent quality tyres.

Guest no1birdman Posted March 20, 2012 Share Posted March 20, 2012 thanks, would buy the disks and pads new, but no calipers in scrapyard, anyone kno w a place might get them, they cost a lot new Quote Link to comment Share on other sites More sharing options...
iansoutham Posted March 20, 2012 Share Posted March 20, 2012 thanks, would buy the disks and pads new, but no calipers in scrapyard, anyone kno w a place might get them, they cost a lot new Just ask for a set off of a post 1990 Sierra, either with discs front and rear, V6 or ABS models. This includes Granada 1985-1994 models as well. As said though, make sure you get the carrier bracket that the pads go in as well as the 240mm one is too small. Whereabouts are you as I may be able to help you out with a set or locate some for you. Quote Link to comment Share on other sites More sharing options...
iansoutham Posted March 20, 2012 Share Posted March 20, 2012 Also, just re-read one of my posts above and realised I put a typo on the wheel cylinder size. I put 19mm, which is the standard size for 1986 onwards models, what I meant to put was that you need 17.8mm diameter wheel cylinders as they were the ones on the 1983-1985 models with smaller rear drums, which work well with the front brake mod.

iansoutham Posted March 21, 2012 Share Posted March 21, 2012 Thanks, I am in stoke on trent Not local to me then, I'm in Kent/SE London. I will sort out the details of a friend who lives near Bolton who may be able to post a set of calipers up to you. He breaks Sierra, Granada and other later Fords.
