Your comments about vented rear discs and solid rear discs has me worried. I have just replaced my worn vented discs (2003 3.2 Omega) with new pattern solid discs. Is there a risk of the pistons coming out of the cylinders when the pads are worn?

Why? As GixxerChris eloquently put it a while back ..... when asked if you want vented or solid, it's not a choice like do you want sugar in your tea?

If you have vented discs at the back, you NEED to replace them with another pair of VENTED discs! The solid discs are half the thickness of the vented discs & when the rear(?) pad wears, the piston behind will fall out & spray brake fluid all over the place & you'll have no brakes!
FIT ANOTHER PAIR OF VENTED DISCS NOW!

Methinks a mixture of limited technical understanding and knotted purse strings

Why else replace one type of disc (as fitted as oem) by a different type?

Yep ask Mike Dundee, it happened to his car.

It's a shame VX didn't make the two types a different diameter so it wouldn't be possible for such a cock up to occur 

Terry,get them changed ASAP mate before something bad happens

Vx dealer gave me solid front discs for the 53 plate Corsa, when they are actually vented on the ABS model.

No apology from them. .....Typical.

The vented discs I exchanged them for are  are much wider.

I should hope so. Can you image how thin each side of the disc would be if you made a vented disc as thick/thin as a solid disc

Yes, and they dont need to wear much either.

The outer piston will pop out dispensing brake fluid everywhere. I had to do a quick repair to Mick Dundees after this happened in a field in York!

Good word! Is the the same as spraying?

Too long ago for an old bugger like me to remember

Today I measured the disc thicknesses; new solid disc .476". Old ventilated disc .703" where worn, .750" on edge (unworn). I shall change them Saturday. Thanks to you all and the forum for pointing this out.

I did once lose all brake fluid on a Peugeot 505 estate. The rear brakes were self adjusting drums, and when the linings wore out the pistons popped out of the cylinders, resulting in total loss of fluid and thus of brakes. The incident is memorable in that I drove the car home towing the wife in her Senator, acting as a brake. She happened to have the computer on fuel economy setting, and was amused to see it recording an amazing high mpg figure.

Glad youre in process of getting it sorted mate 

When you replace the discs it says in the guide to back off the shoe adjuster...... couldn't you simply leave the handbrake off and that will allow the disc to come off?  ive only done pads so far

Absolutely. We've seen it before.

Additionally, you may need to inform your insurance that your have "modified" the brakes, as its no longer to spec

Likewise & I've had an Omega & Senators for over 15 yrs

You might be lucky

When I have replaced worn rear discs I found that the brake shoes had worn a grooves in the drums and I had to back off the shoes to get the drum/discs off.
