Title: 288mm brake measurement help?
Post by: tweed on 13 August 2011, 21:22
Has anyone fitted new front pads on their 288mm in the last month or less?

I need to know the distance between disc face to the caliper face. does that make sense? :laugh:

I want to buy some hispec four pots and need to make sure the four pots don't stick out further than the original 288mm caliper from the disc when they have new pads.

Can anyone measure that for me or post a diagram with said measurement please, pretty please  :kiss:

Tbh this time not really, the only measurement they show is: 288X25MM 5/100 I am guessing 25mm is thickness.

No mate I need to no for clearance. caliper to wheel. look at the link I posted of the hi spec caliper that should help you understand what I'm trying to say  :grin:

I've got ya, can't you slide your standard caliper out to its fullest extent without the pads fitted and trial fit your wheel to obtain the clearance measurement?
The thing is these calipers run quite close to the standard alloy wheels and the clearance will obviously vary dramatically depending on wheel choice.
On that hispec diagram it illustrates there been 17mm from the outer wheel mounting face of the disc to the inner face of the wheel, what wheels is this for? What size and ET have they used as their test rig for their 4 pot calipers?
I reckon this is going to be a case of buying the calipers ( do they utilise the standard discs?) and bolting them on to see what you've got then possibly spacing the wheels out to suit.

the link you posted is for 280mm discs so i'm guessing that you are trying to adapt the calipers to fit 288mm discs ?.If that's correct do calipers come with brackets or do they utilise the originals ?.If they come with brackets are you not going to run into problems there by trying to fit calipers to brackets made for 280mm discs ?.Same problem if the calipers use standard brackets ???.Clearance would depend on wheel size and wheel offset if you can actually get them fitted to the hub.

Thats a good idea that I didn't think of. I don't know what they have used to get these measurements  :undecided: It's a kit, you get caliper, carrier, disc, pads, lines, fluid. This is the thing I can't space my wheels out any more than what they are. I would like to bring them in a bit more.

It is a kit, everything is included as above. I can get 280mm or 300mm and I'm not going to be running crazy power, 200/250bhp. So I'm going for the 280mm. I need them to fit under my Schmidt's or I'm going to have to buy smaller lips. and thats not really a option for me  :grin: 

Going to be doing some work on it this week so will take the measurements and update.
