Fitting 306 Brakes - Problems.

[springs 0]

i tried test fitting my 306 1.8XS brake callipers today only to find that they don't seem to fit. i tried it with a disk on the car and it looks like it only gives a few mm clearance for pads... any ideas? is there a special way to fit these?

If you are using 1600 front hubs that is your problem. You need 1900 front hubs to use 306 brakes.

they are 1900 hubs ( or so i believe)

From the driveshaft nuts I don't think they are, but could be wrong. If the shaft nuts are 32mm AF then they are 1600 shafts and hence hubs. 1900 stuff is 35/36mm AF shaft nuts.

So do the calipers fit on with the disk fitted? Do you have any photos of the disks fitted?

 

In them photos it looks like the pistons are pushed out, try winding them in with a G clamp or something.

i'd investigate your hubs but i'd say they where 1.6

the ones i took off the car which i swapped for these ones i tried using the hub nut on the new drive shaft and it wouldnt fit..

 

i brought the hubs / shafts off here from a member off here

I know this is generally the norm. Only reason i question, is one of my shafts its 32 mm, the other is 35mm. The 35mm has a cover, which goes over the nut, then the pin, the 32 mm has holes in for the pin already.

Definately 1900 hubs, as im running 307 brakes on them.

Have you actually tried fitting both the disc and the pads?

 

Don't forget the tophat part of the disc means that the actual disc faces sit fairly far back, plus once the disc is between the caliper carrier the you have the thickness of the carrier in which the pads will fit.

 

On top of all this the caliper will then slide over and you should be fine.

ill have another go tomorrow with the disks / pads and see how they fit..

 

also for those that changed calipers.. what bolts did you use?? ive for some caliper bolts from put but they look a bit short when using the 306 calipers

well i test fitted them on sunday with full disks and pads and it does fit on the part worn pads i have.. it was down to the way the caliper was designed and how they put the pads in

 

my bad.. now just have to take the old pads back to GSF as they gave me the wrong ones
