Front Disk brakes

[moking joe]

I recently I seem to have broken a front wheel stud, not sure when or how.

I thought I would be able to just tap it out and slowly push in a replacement. But the head of the stud seems to
be obstructed by a fine ridge line which circles the brake. Not sure if its 7" or 71/2" disk or whether that matters, the stud appears to be 35mm. Mixing my units here !

Could anyone tell me whether I really need to remove the whole assembly here, of should I be hitting the stud harder.

Thoughts much appreciated.

Just trying to remember back to when I changed mine.... I seem to think I managed to do it with everything in-situ. But if you undo the centre nut and the disc bolts perhaps that would give enough play to do the job

I managed to tap my studs out in situ but that was on the later 8.4" setup.

Never had the smaller discs myself, but looking at pictures I'd think that you should be able to get the studs out without dismantling anything. I would certainly think you should be able to un-seat the studs even if there is not enough clearance to get them out, so this suggests that you are not whacking them hard enough! Studs can be very tight and I usually take the flange off (8.4" discs and rear) and press them out with a socket over the 'head' of the stud to prevent any risk of damaging the flange - I know it's unlikely that you could bend a drive flange or rear hub flange but I like to do things properly to be on the safeside.

Specified torque for wheel nuts is only 44 lbf ft and it's easy to overtighten them using anything more than a cranked wheel nut brace - most garages use air-wrenches on the same setting for everything from Minis to 4x4s and if they don't snap them like carrots they can start a failure.
Pedantic, I know, but I always put my own wheels on and use a torque wrench.

Thanks Guys,

I had another look today and they are 7.5" disks.

I can get the stud to move but its head is obstructed.

I thought the disk and the section containing the studs were one piece, looking at the
part on Mini Spares, mini Sport web sites, but it seems not !!!

Any further advice appreciated, studs should arrive monday I hope.

I just got this offer for Mini & Cooper Drum Brake To Stock 8.4 Disc Brake Conversion Kit by email.

Mini & Cooper Drum Brake To Stock 8.4 Disc Brake Conversion Kit
It is very common these days to find Minis here in the States with drum brakes.
To convert to disk brakes you have numerous choices but most of them first have to be factored by the wheel size you have or want to run.
Various options are available with the 7.5" size rotors (for use with 10" or larger wheels) or the 8.4" rotors (for use with 12" or larger wheels).
No matter how well your Mini handles, you still have to stop sometime, and if the car in front of you has ABS you'd better be able to stop right now!
This special Mini Mania kit provides all the parts needed to upgrade from drum brakes to stock 8.4" disc brakes.
THIS CONVERISON REQUIRES 12" WHEELS.
We recommend one of the Haynes manual if instructions are required. Part # 527 or 646.
NOTE: These are NOT assembled units; parts assembly will be required!

US$1,012.27

Seems a bit steep to me........considering the set of discs and shafts on fleabay at £49 !!! But they are in the UK of course

What exactly would one need to buy?

Would you do all four wheels or just the front ones?

[Nigel(no top)Sykes]

If iwere changing the studs I'd do all 4 wheels. Discs would be the front only
