is there a limit to how much weight wise you can fasten to a 4x4 saph hub ?

ie heavy brake calipers

anyone know it fixing a caliper weighing 8kg to a saph hub would cause any probs ?

matt

 

anyone ???

someone must know !

 

jeez , are they tractor calipers , thats as much as a wheel weighs ! Cosworth wheel bearings are shit anyway , i'd be tempted not to !

 

there off a range rover sport lol

so thats a no then ?

matt

 

Look like this do they?

you can just see one snuggly fitted behind the wheel aswell

 

very possible yes ryan

just weighed one it actually weighs 6kg

how heavy is a big ap caliper then ?

 

and its 100% possible, as this is what these are off

Just checked and there about 2kg more than the AP 6 Pot variety

But there only just hevier than standard items if i remember rightly

 

have you got them fitted yet ?

any pictures of the brackets you had to make ?

also have you removed them two big blocks from the back of each caliper ?

and lastly for now lol what size are your discs ?

cheers ryan...............matt

 

Yes there fitted and all finished.

Here's a rough bracket, they've been refined slightly now.



yes removed the 2 blocks at the rear of the caliper.

355 disc's, with a 60mm Pad Area. Very few company's do these. Mine are Alcon.

Bells are also custom made aswell.

 

i take it a 3dr hub is different to a 4x4 saph hub ?

me and gracie are going to try and make some brackets lol

and my discs are only weedy 310 x 28mm ones lol

if you have any more pics ryan please put them up lol especially the bracket

matt

 

ok next question pmsl

just been looking on the hi spec website re bigger rotors for my bells and they do some 325 x 300 mm rotors with the same pcd as the bells i have now,

it says the pad swept area is only 50mm, would this be ok as opposed to the 60mm that the pads are ?

as you can see im new to all this lol

matt

 

Matt,

get 330mm x 32 rotors on the fronts,will be well better.

 

dave, the hi spec shitehole place only does 325 x 30 mm max,

if you can get me some 330 rotors and bells for a fourbie for 200 notes be my guest pmsl

matt

 

well Matt,

i ave just got new ones myself...330 x 28.

i have my old 330x32 here.

only changing them as i needed 28mm wide instead of 32 mm wide.

Some very slight score marks were the caliper has been rubbing,hence changing them to smaller width.

yours if you want them.

no bells though.

 

how much would bells be do you reckon ?

 

Ł120+ i would imagine

 

ok lol next question

with my 310 discs it looks like the edge of the caliper is quite close to the inside part of the wheel (tsw imolas)

what im asking is, on a 4x4 saph caliper from when the pad ends and the caliper bit goes over, is it quite big ?

my only worry is would these big brakes actualy fit inside the rim of a comp mo 17" rim ????

are they warped or anything dave ?

just not sure now that ive had a look at the existing setup wether there will be enough clearance pmsl

what do you reckon, dave / ryan ?

matt

 

think u will struggle to get them under 17's

u dont want pad overhang.

unless u have access to a lather and mill for cheap engineering i wouldnt bother and look for a cheap second hand AP kit.

Cheers

 

lol, no they are not warped Matt.

i would say you are going to struggle doing all this and then it does not fit.

sell them and buy a used ap kit.

imo.

 

lol, ok so idealy need a 60mm pad sweep then ?

what wound i need to mill, turn ?

my super ebay deal is going down the pan pmsl

 

just done some measuring up, on the focus rs brembo, from the end of the pad to the outer edge of the caliper is about 20mm with 50mm pad sweep / depth

on the fook off caliper its about the same but its a 60mm pad depth

so theoretically the only thing that would stop it bein fitted is the pad depth re overhang as the distance from edge of pad to furthest part of caliper is the same on both of them

os overhang is no good then ? lol

 

MSN Matt

 

Dunno if its been said, can't be bothered to read whole thread.

Surely a heavy caliper won't affect bearings. Its bolted to the hub, not the wheel. Would be just the same difference as haveing 16KG in the boot

 

tof has these brakes on his 3 dr and has had no probs

 

the big range rover ones ??

how big are his wheels tho ?

 

17 inch mos.

yeah big silver ones in your pics

off a range rover sport.

he had it on trak last weekend and said brakes were amazing

 

right lol whats his user name etc msn etc pmsl

 

he has got pics etc..

he made brackets himself so he will have all the know how on how its done

pm him, his user name is Toff

 

do you know what size braks discs he uses ?

matt

 

he is online now

can answer all your questions

sure his disks are same as mine

355's

 

how the hell do you get 355's on a 17 inch wheel lol

 

can only be done under MO's i think

 

 

would the six spoke mo be the same as the 5 spoke re the clearance bit do you reckon ?

 

reckon so but best ask martin hadland or someone with more experience.

had to shave abit off my caliper and repostion wheel weights but apart from that they fit no probs..

they are also 8 " wide but not sure if that makes a diff over the 7.5 " ones

 

thanks very much euan

if toff can fit 355's on then surely i can get 330's to fit ok ?

muchos gracias

 

yeah i would say defo 100% they will fit...

hope to see them on the car soon

 

so do i mate lol

thanks for all your help, just hope toff logs on soon and replies

 

a standard 2wd cossie 4 pot weighs 5kg, so i would say you'd be fine

 

Marco (Lenny) has 355's on his 3 door and has RL7's
