Rear disc and pad change, right pads? - 306rhys - 19-08-2015
I've got a spare rear beam that I'm changing the discs and pads on before it goes back on the car.
I ordered new brembo discs and pads - cheapest ones off eBay
the pads arrived but 3 are the same and 1 is different which seems odd.
3 of the pads have nipples (not the best descriptive word) and the other one has a dimple
having a look through this thread
http://www.306gti6.com/forum/showthread.php?id=20261
it says that the pads with nipples go against the piston in the notches, however having a look at the pads that came off the beam it looks the opposite way round, the ones with the dimples went against the piston and the nipples went against the calliper.
Do I need 4 pads with nipples or
2 pads with dimples and 2 with nipples?

I'd say they have given you one wrong one basically.
RE: Rear disc and pad change, right pads? - welshpug - 19-08-2015
that's fine, just put it on the outside.
RE: Rear disc and pad change, right pads? - HDi--Power - 19-08-2015
If the ones that came off had a dimple against the piston then they were fitted wrong
RE: Rear disc and pad change, right pads? - Piggy - 19-08-2015
Am I being dumb... But I am 99.9999% sure you need the dimple on piston side to stop the piston winding itself back in?! It goes in one of the piston slots no!?

Ah yeah of course. Makes no odds if dimple on outisde! Silly me
RE: Rear disc and pad change, right pads? - 306rhys - 19-08-2015
Thanks for the replies, ill just make sure the one with the dimple goes on the outside saves the hassle of sending them back
But yes I'm pretty sure the bump locks between the piston so looks like the older pads were fitted incorrectly
RE: Rear disc and pad change, right pads? - Piggy - 19-08-2015
Afaik the old ones were fitted right...
Not sure what Hdi-Power is on about tbh
RE: Rear disc and pad change, right pads? - HDi--Power - 19-08-2015
The bit that sticks out fits in the piston, the odd one that he has in his set must go on the outside, remember the dimple is the hole. so his old ones were fitted incorrectly.
RE: Rear disc and pad change, right pads? - 306rhys - 19-08-2015
This is what they mean by notches in the piston, the guide on .net also says the bump on the calliper is supposed to slot into here (sorry for the screenshot don't know how to edit pictures yet)

I think Piggy's misread the OP, took me a minute then TBH.
RE: Rear disc and pad change, right pads? - HDi--Power - 19-08-2015
I think he has his nipples and dimples mixed up
RE: Rear disc and pad change, right pads? - 306rhys - 19-08-2015
It fits like this
Has anyone got a picture of what this pin looks like on its own?
Only reason I'm asking is because I can't remember taking one out when i removed the pads but I kept everything I removed so if it had one fitted it'll be about somewhere, if not anyone know the part number?
RE: Rear disc and pad change, right pads? - Jonny81191 - 19-08-2015
Meh, it's just an R-clip, as long as there's a pin in there it'll stay in (I see loads with split pins in). Just make sure there is something in there, otherwise your pads will go walkies.
RE: Rear disc and pad change, right pads? - Piggy - 19-08-2015
Yes I do have my dimples and nipples mixed up.
May need to re-evaluate my bedroom tactics.
RE: Rear disc and pad change, right pads? - 306rhys - 28-08-2015
Just tried putting the pads back on, but they don't fit? I've rewound the piston a lot and they still seem to be like 2/3mm too big to go back on. Any ideas?
unattatched the handbrake cable. This is whilst the rear beam is off the car.
RE: Rear disc and pad change, right pads? - Toms306 - 28-08-2015
Wind the piston back further lol... The locator lump is definitely in the cut-out yeah?
RE: Rear disc and pad change, right pads? - welshpug - 28-08-2015
yeah, needs to go back more
RE: Rear disc and pad change, right pads? - Eeyore - 28-08-2015
wind it in and pull the slider around?
RE: Rear disc and pad change, right pads? - 306rhys - 28-08-2015
Ill give it a good wind again tomorrow and see if thats it
RE: Rear disc and pad change, right pads? - cully - 29-08-2015
check sliders are free if they are wind back the piston more
RE: Rear disc and pad change, right pads? - 306rhys - 29-08-2015
Yeah sliders are free, will give it ago now
Will clamping the piston back in work?
RE: Rear disc and pad change, right pads? - Toms306 - 29-08-2015
The piston needs to be turned back in, clamping it won't do anything.
