Which would be why they use cooling rotors on the axles. Disc brakes can suffer from fading if they are used heavily, but they are an excellent system - that's why you find them on cars and lorries too.

Hello flying pig.
I am pretty much sober now and i see the big mess I have made.

In your statememnt shown above you say that disc brakes are an excellent system. Just before that you say that they can suffer from fading.

This to me just does not make sense.
On trains they will be used heavily and even if ventilation helps they will be shockingly expensive.

Last night when fixing that bogie I was on about we went to order the brakes and they were £10,000 just for the discs.
I only had to pay 500 buying pads.

Pads and discs are essentially the same, a pad is forced onto a disc (disc brakes) and pads are forced onto wheels which act in a similar way.

Wheel pads just cool better, the only downside here being in wet weather grip may not be as good.

(sigh) I can tell this is going to be a veryexpensive day for me.

Thanks for all your help.
