Steve and Becky Posted October 25, 2004 Posted October 25, 2004 We have our front and rear (westfield) Uprights in place, Going to be using (westfield) wheel cariers...Wondered what my brake options are? Want disks front and rear, Anyone any ideas , or advice? I was thinking of putting venteds on the front? Quote
adhawkins Posted October 25, 2004 Posted October 25, 2004 I was thinking of putting venteds on the front? Don't think there's any point to be honest...it's not as if you're stopping a big heavy car. Someone will be along to tell me I'm wrong soon enough Andy Quote
Blatman Posted October 25, 2004 Posted October 25, 2004 Vented discs are not required. Ordinary Cortina discs are just fine. There are a couple of places who'll drill them if that floats yer boat, but vented discs just add weight. What vehicle are you building? The choice of discs or drums at the rear is determined by the rear upright (and what the donor car has in the case of the SDV), unless you have a live axle... IE, the choice of discs or drums has probably already been made for you, if you didn't specify when ordering the car what you wanted... Quote
Blatman Posted October 25, 2004 Posted October 25, 2004 Going to be using (westfield) wheel cariers Also, this confuses me a little. If you mean hubs (hubs attach to the uprights/stub axles at the front, and to the upright/drive shafts at the rear. Hubs and uprights are often confused when people are attempting to describe what they are looking at...) then they ain't Westfield items, they're Ford... Quote
Steve and Becky Posted October 25, 2004 Author Posted October 25, 2004 They are both Front and Rear Uprights from Westfield. Bot allow disk brake option to be fitted. What id like to know is what brake disks and calipers will fit with the Westfield Uprights. Hope ive explained better. Quote
mb893 Posted October 25, 2004 Posted October 25, 2004 Any Cortina (MK3,4,5) style caliper/disk on the front and a Sierra rear caliper/Escort Mk3/4 front disk on the rear. A fair few companys do some rather saucy front multi piston front calipers and either plain, grooved or drilled disks front and rear. Vented disks are not needed as has been said. Quote
Blatman Posted October 25, 2004 Posted October 25, 2004 If this is an SEi, and not an SDV (I know very little about the SDV, and you haven't said if it's an SDV or not. It may make a difference...) then Mk3 Escort front discs are what fit to the rear hubs. For the rear caliper, any Ford rear brake caliper from any Sierra or Granada that had rear disc brakes fitted as standard. Quote
conibear Posted October 25, 2004 Posted October 25, 2004 Blatman, my front vented discs get very hot during 20 minutes of track use, I'd of thought the vented type would help, although not everyone tracks theirs cars. How much of a weight saving is there and why does WFD sell the vented type if there not really necessary I'd agree though if I was buying again it wouldn't be the vented type, but I'm not convinced there not necessary for my use Ian Quote
CedricTheBrave Posted October 25, 2004 Posted October 25, 2004 May be your cars too heavy then ConiBear I think that the vented disks are better for track days but the difference is really minimal. also depends which track your running at Quote
Blatman Posted October 25, 2004 Posted October 25, 2004 why does WFD sell the vented type if there not really necessary Er, marketing. Same reaon why they don't give *everyone* an RAC bar as standard. They'd have no market for them as upgrades if they did... my front vented discs get very hot during 20 minutes of track use, I'd of thought the vented type would help, How hot? Ever had any temp paint on to see what temps the discs are reaching? I think that with a suitable pad material, they'd be OK for temps up to 500-600 degrees, and probably be fine at a continuous 2-300 between stops. The beauty of a Westifeld is that there is far less mass to slow down, so the brakes don't get worked nearly as hard as you might expect. If they aren't fading or blueing, then they're not getting too hot, so the venteds would help how? Standard Cortina discs used to have to cope with stopping a 1.5 tonne car full of 5 people, plus luggage towing a caravan hurtling downhill in the lake district... They'll be fine on a car weighing *much* less, even when they are put to arduous use. I don't recall *anyone* ever saying that the brakes were so hot that they fitted vented discs which cured an overheating brake issue. Quote
conibear Posted October 25, 2004 Posted October 25, 2004 I'm just trying to convince myself not to change them really My 4 pots cannot be used with standard discs so I'm knackered and I'm not getting cheque book out to save 0.5kg per corner. They get hot enough that you can't touch, but as you say Blatman probably take a shed load more heat to warp em. I have to stick with em then Quote
Steve and Becky Posted October 25, 2004 Author Posted October 25, 2004 So Escort mk 3 disks, and sierra calipers for the rear, and Cortina disks and calipers for the front.... are the latter easy to source? I still fancy vented at the front just for that sake of it really... Im building an SEI, it was going to be the SDV, mut had a change of mind early on in the build so westfield kindly swapped a few parts for me :-) Thanks again peeps Quote
Nick M Posted October 25, 2004 Posted October 25, 2004 My 4 pots cannot be used with standard discs so I'm knackered and I'm not getting cheque book out to save 0.5kg per corner. What calipers are they ? And you can actually save a lot more than 0.5kg per disc - it would be more like 1.5kg, possibly more if you went for lightened discs. FWIW, I used Fluke lightened discs on my car with slicks and never had any issues with excessive heat. Whereas I used to struggle to get the vented discs up to temperature. Quote
conibear Posted October 25, 2004 Posted October 25, 2004 Nick, the front calipers are Westfield 4 pot (bremsport) i believe, there for vented type discs only, as you know these cost a lot of dosh, so I will stick with em, although your right I'd bet I save more than a kilo per disc. FWIW, I fit Flukes lightened discs to the rear of my SEIw, I saved just a bit less than 900g per rear disc, which was TBH disappointing as I was led to believe to be more like 1.5kg each. Oh, my scales are very acurate cheers Quote
Nick M Posted October 25, 2004 Posted October 25, 2004 Don't the Bremsports have spacers in them to accommodate the vented discs ? Or did Westfield sell two types (vented and unvented) and get them made to suit each disc type without spacers being needed ? FWIW, you'd see more difference with front discs weight wise, not least because there's more meat on them to begin with. Quote
