Front Brakes

The following brakes are equivalent

Bremsport M-16 (mine)

Outlaw M16 http://www.outlawdiscbrakes.com/m16.html

Wms (WORKS MOTORSPORT) www_worksmotorsport_com

Compbrake B-16 http://www.compbrake.co.uk/compb16.htm (interesting claims about their development of this product!)

Claimed weight (per calliper) is 1,757g which sounds credible

My callipers had a spacer between the two sides which increased the gap, undoing the bolts and the calliper falls apart nicely. I took this out and the callipers meet perfectly in the middle of the disk (with Capri upright). With the spacer in it might be right for a vented disk, not sure. There are some small rubber o-rings so be a bit careful with this!

PADS

The Outlaw website has useful information on their version of this and they claim to take the following pads:

PFC 7754.16,

Hawk HB237,

There is some suggestion that these can use the Wilwood Dynalite pads (EBC Greestuff dp2001) but those pads don’t have a hole for the brace bolt.

The EBC Greenstuff DP2010 series of pads have the large hole (compatible with Outlaw 2800, which looks remarkably similar to the Outlaw M-16).

The only concern is the pad thickness, as the Outlaw site suggests that these need a thicker pad than the 2000 series (no specific mention of the 2800).

Wilwood 7212, interchangeable with R301-12, Pad 7812: these are thin-ish

Wilwood 7216 is thicker (so better)

7754.**.16.04 HB237.625 R301-

www.mnrltd.co.uk sell Hawk pads at £53 a set

www.ebcdirect.co.uk sell the DP2010 pads at about £26 a set

Hawk HB100 pads available in 0.480 and 0.625inch thicknesses. These are 100mm wide, which is not perfect (bit of slop) but not bad. These are what Westfield used to supply with their Bremsport callipers (I know this as I got a set of the 0.480 pads from them). The only problem is that the brace bolt hole will need drilling larger (although the existing hole is in the right place, so that is trivial. Also with my 13in wheels I will need to trim down the excess from the back of the pad to allow wheel clearance. The hawk range of pads are available from http://www.cambridgemotorsport.com/ (£42.86 not sure on VAT and delivery for a set) this site includes a good list of the sizes available, although doesn’t include the HB237 pads! These fit the disk nicely, so I think that they are the ones to go for.

HB237 pads are available from http://www.gprdirect.com/ in a choice of thickness (12mm or 16mm) and compound. Note the HB237 is labelled here as 99.06mm by 61.72mm: (£40.96 + VAT + shipping).

The only difference between HB237 and HB100, seems to be the backplate size.

DP2039 may also fit (Greenstuff pad, these look a better size, i.e. 100.6mm, but are pricey). This number doesn’t seem to show an image on their website, which is a bit scary.

UPDATE:

I asked the LocostBuilders site:

Comments: EBC greenstuff never get properly warm for the road in such a light car, so not good.

Volvo 240 MGB MGB576 is suggested, these are from MINTEX (and use the 1144 compound). The problem with these is that they are 3mm too short (ideally 100.6mm long) and need filing out for the brace bolt, using shims also may help stop the pads gouging the calliper, which is seen as a potential source of problems. These pads are well priced though (around £6 a set)

I got a set of these pads and made the modifications:

Brace bolt mods are trivial,
13in wheel mods were straightforward, trimming excess backing,
building shims isn’t so easy. The gap between the pad backing and pistons is about 1mm, so making a spacer that is 3mm thick at the end is not nice. I am worried about Mr SVA, so for the mean time I will go with the Hawk pads.
NOTE also the Volvo pad overlaps the disk, so the pad would need trimming down (to avoid loss of brakes when the pad touches the pad).

I managed to get a set of Hawk pads (Westfield old stock for £10). The pad sizes are right, the brace bolt needed drilling (no problem), and I needed to trim the back plates to fit under 13inch wheels. They look good. Some report these as a bit grabby on the road, but time will tell.

DISKS

I have a Capri upright (modified for Phoenix/Striker by STM).

Not sure what disk I need.

It needs to be solid (12.8mm seems to be the standard, which is ½ inch in real money).

Two sizes exist 244.5mm (RS2000 and 1.6 Escort), and 247.5mm (others). I am going with the later and hoping (larger size has turned out to be perfect). Yup that seems to fit nicely.

Mnrltd do really nice drilled and grooved disks for these callipers, but at £110 I am too mean. There is a suggesting on the “designing your own braking system” on the Rally design website that drilled disks are not great with carbon-metallic pads. So the MNR combination may look nice, but might not be too clever. Not sure what to think about this.

ODDS and SODS

Disks bolt on using 4 hi-tensile bolts. Originally these had disk brake tabs which bend over the bolt to stop the bolt loosening. This isn’t a bad idea as a disk falling off is not a good failure mode. Also the heating and cooling of dissimilar metals and vibration will both help release this. Various www.locostbuilders.co.uk are happy with threadlock for this. I managed to find some (ridiculously) priced stainless tabs (e-bay £5 including shipping from Australia!), they are obtainable from Westfield (72p each) non-stainless.

Tabs for mounting callipers are similar (but different sizes), I managed to clean and reuse the ones which I had (damn I am mean).

Sources of information:

All greenstuff pad images can be accessed using http://www.ebcbrakesdirect.com/car/image.asp?image=DP4010 where you just put the relevant number in at the end (in this case 4010).

http://www.brakeparts.co.uk/ are the best value for brake stuff, and mighty quick. At least get a price from them first before going to your local motor spares place. They also have good technical details on their site. Only problem is after 30 pages it gets a bit snotty and thinks you are just window shopping. Registering or purchasing distresses them.
