Compare disc size with almost any other car, and the discs are disproportionately small. I guess budget comes into it, and ten ton plus stops without fade is probably in industry standard.
But add in how easy they warp(ebc in this case) , rust on the inner edge(ebc don't), fade with anything less than 75% pad material, lack bite, feel and servo asdistance I'm sorry, but they're shit and that's that.
Fit for a trip to the shops and back without spilling anything. But that's as complimentary as I can be frankly.
ANY other car has better bite (more servo assistance) than the omega. Not a mark on the power of the brakes capability fair enough but, Add in a bit of pad ware, some rusty discs after a lay up, a hire car while on holiday, and the poxy things can catch you out first time you stop when back in an omega.
These, ladies and gents, over the life or a set of discs and pads are.... SHIT BRAKES.
