YPVS 350 disc brake thickness

[pouchy750]

The rotors on my F2 appear to be worn.

The manual says the discs should be 5 mm thick, but measuring the thickest (outer) part of the disc, they only measure at 4.5mm

I've measured the worn part of the disc where the pads rub against & it is only 3.8mm. Is this acceptable?

Are the standard discs flat the whole way across & mine are worn from use?

Thanks

I think the service limit is 4.5mm (where the pads grip) so I think they are shot. I wouldn't risk anything in the brake dept. Disc should be flat the whole way accros when new.

Sorry "across"!!!!

If they are that bad then you must be feeling this at the lever.
You should replace the pads when you fit new rotors
