new disks= new pads?

Post by **Hacksawbob** » 16 Jul 2012, 12:50

Do I need to put new pads in when I put new disks in? The existing pads are only about 6 months old and have bedded in to the old disks. Is it better to leave a pads that are broken in or time for a new team to wear in together? existing disk is a bit corroded around the edge and slightly lipped about 1mm (MOT has it as an advisory.)

I think the general rule is to replace them together.

You could leave the pads in but they could increase the speed of wear on the disc (that said, my view is that the pad would confirm to the disc not the other way round).

Are you keeping the van? If so, do it properly,

Well I'd like to do it properly whether I keep it or not. I just wasn't sure what was best.

Personally speaking, whenever I have fitted new disks, no matter how old the pads were I always renewed the, and in some cases renewed pistons too, but more so on rear show when renewing drums etc.

Pads are designed to wear down and have a shorter life than discs so I'd have thought you'd be OK to be honest. Certainly BMW changed the rear discs on my Z4 recently and didn't try and sell me new pads (and I can assure you a BMW Main Stealer never misses a chance to sell me something!).

All IMHO and I may be wrong...

ETA: but if there's any doubt there's no doubt, change 'em - cheap peace of mind I guess

T25's are so easy on their pads, if they are only 6 months old I would use them. They will very quickly bed in to the disks and new pads have to bed in too !

Well ive ordered the new pads i'll eyeball them when they come off and see what the wear pattern is like.

If they are fairly new, haven't hardened (which they won't have after 6 months) you just face them up on glass with rough emery cloth until flat (much easier bedding in to the perfect flat discs)
Really no need to buy new pads.

However, I would say with brakes you get what you pay for.....so get branded not some non descript.

ATE/Brembo/Pagid all good.
