Heavily scored brake discs dangerous?

[Jack Johnson]

Are heavily scored brake discs dangerous, as long as they arent too
thin? Does it just mean that any new pads fitted will just wear
quicker?

Is it safe just to replace the pads, even just temporary till I get
some discs and somebody to fit them?

Yes. Provided they are not too thin or warped a scored disc may even
perform better than a smooth one.

There is a wear limit stamped on the edge of the disc (probably now
unreadable), roughly 5 mm less than the thickness new. if the disc is non
vented then a minimum would be about 8mm, vented discs vary too much to
guess. Look at the edges of the wear area, if there is a deep lip, say
about 3mm deep then they are too far gone, up to about 2mm would be ok-ish
though.

The new pads wear a lot quicker, & pads and discs are comparable in price.
If they're not below limit then they're usable though.
