Wheel off, caliper loosened, disc is now unattached?
Discussion
Just checking caliper operation on a binding font wheel (MR2 Roadster), having removed wheel and rotated caliper up to get at the pads (very stiff - corroded into place partially) the brake disc is now free to flop about...
Shouldn't the disc be secured with a couple of bolts?
My understanding is the studs that come through the disc and wheel are the main fastener, but I'd expected the disc to be located by it's own bolts...
I haven't had time to remove another wheel and compare - it's going home time - but come Monday at 08:15 I'll be back to compare.
In the meantime, any comments from the fount of knowledge that is PH? And thanks...

What?!
Hi, you would not believe how many cars we have had to bring to the garage on the "spec" when so called DIY work has been carried out and wrecked the brakes, striped threads and rounded off nuts not having the correct tools it looks so easy in a workshop manual but if you work on a key board all day every thing looks easy.RONV said:

as others have said the screw just locates the disc its better to have one as if the diisc is loose dirt and rust that builds up unevenly under the disk so if it moves round on the hub if you remove the wheel then you can get brake judder due to the disc not sitting flat on the hub , best to clean every thing up and put a tiny smear of brake grease on the hub face when you reasemble along with the locating screw if it has one ( do not do it up really tight just so it contacts the disc grease it first )
I have a Roadster, and I'm pretty sure they are not fixed to the hub. They don't actually need to be, as others have said. With the calliper in place, they can't come off anyway.
One tip, if you brakes pads are at the end of their life, that can sometimes cause them to stick, as the exposed calliper tends to corrode, plus the long extension of the calliper can sometimes cause it to 'twist' a little, and be less willing to retract when you release the hydraulic pressure.

Incompetent tossers had left the old one in the caliper when they changed the pads.
Thanks for the replies. Especially Ron (who needs to know this is the first time I've been behind the wheels, having had it serviced at a main dealer for the last four years, so somebody there has decided not to re-fit the grub screws for whatever reason).
The calipers are moving better now - after de-corroding - and I think I fitted it the right way round.
I'll be removing the other one this am to see how many grub screws I need to retrieve from the local dealer.
Edited to remove further sarcasm.

Hi,this a job is for a garage to do your life and others depend on the braking effect of your car and any mistake you crash and damage your car and maybe someone else's you need the correct tools and equipment and knowledge to carry out the task. Ron.
I know this is a troll but:bks! Anybody with an ounce of common sense and can operate a torque wrench could do this. Even a trained chimp could do it (Kwik-Fit seem to employ a lot of them), I would rather do it myself and know it's right than let some YTS youf who's probably still pissed/stoned from the night before do it as a so called professional.
The OPs question does seem to have been answered, hopefully they crack on and get the satisfaction of knowing they have fixed it themselves.
