Ap disc replacement

[flatout]

Just a quick question.

When replacing the AP front discs, does the unit come complete or is it just the outer section hence a need to unscrew and attach to the existing bell?

Thanks

comes without the bell and lock nuts/bolts (CP2494-18 x2 Disc Bell Mounting Kit)

but you can order i believe a set with the bell fitted if you ask for the right number

if you do it yourself you will need two sets of nuts/bolts from AP and the appropriate spanners and wd40 and a whole host of patience (the bolts only get torqued to 14nm so you will need a very low nm torque wrench)

you can get the front discs off and nw ones on WITHOUT taking the callipers off, just need to remove the pads.

I can't seem to find a guide on the pad replacement for the front AP set up, sounds like Shimmy knows and that it's probably on here somewhere. can somebody point me in the right direction? Discs and pads are here and I'd like to get them on, cheers. I'm guessing from what I've read here that the calipers don't even need removing which is a bonus.

1. jack up car
2. front wheel off (no need to remove callipers for pad OR disc change)
3. allen key (6mm i think) to remove two allen bolts (items 17 x 2) on side of calliper
4. slide out two tubes and anti rattle clip (item 9 - note arrow should point up)
5. from the back of the calliper push against the metal of the pad to compress pistons as far as possible
6. slide out pad, slide in new (check same shape pads)
7. repeat for second pad
8. slide in tubes and anti rattle clip (arrow facing up)
9. push in bolt and just nip onto thread
10. push in other bolt and just nip onto thread
11. tighten both with allen key to hand tight (no need to overtighten)
12. clean out AP logo
13. fit wheel
14. torque bolts about 110Nm
15. jack down car

then repeat other side

where people make mistakes is on the removing allen bolts
(item 17 x 2), if you dont remove them easily or if you dont locate the bots right or overtighten them you can bugger the thread where they locate as there are helicoils inside.

Wow that does look easy. Thanks a lot shimmy, I'll be doing that this sat morning

I will replace AP discs with PFB disc that I have at home now. Do I have to remove the caliper or not? How??

Best regards

no you dont

take out the pads and release the disc bell with the two allen key studs and the disc and bell come out at an angle with the calliper in place (you might have to make sure the pistons are in if the pads were low)

when you fit the AP bell to the PF discs use new lock bolts and only tighten to 10Nm starting at alternate sides


getting the old bolts off is the hardest bit
