Here are some brake bits, basically overhaul kit for standard 4.2 AP Racing calipers, I know some codes have been posted before, but I thought I'd add these as basically the J or K suffix is the size, so you can order a combination to make up the number of seals you need. Each piston has 2 seals, so front is 4 piston, 2 x 1 5/8" pistons and 2 x 1 1/5" pistons and rear is 2 piston 2 x 1 1/5" piston. And a seal kit, is per caliper.

Description: Brake seal kits Details: AP Racing CP4519-K 1 5/8" Unit cost: £8.24 No. required: 2 Total: £16.48

Description: Brake seal kits Details: AP Racing CP4519-JJ 1 1/5" Unit cost: £13.43 No. required: 2 Total: £26.86

The no. required, I assume is per axle? So if I wanted to do both front and rear I'd need 2 of the -K seal kits, but 4 of the -JJ seal kits?

Hi,

I've just checked my invoice from DG and for both front and rear calipers (i.e. All 4 calipers) I bought:

2 x CP4519-K 1 5/8" Seal kits
2 x CP4519-JJ 1 1/5" Seal kits

I hope that clarifies things, got me confused too.

You may also want to add some new bleed nipples to the order, they're only about £2.50 each (CP3720-173) and well worth changing when everything's out, oh, put some covers on them too.

And, don't forget the brake fluid, I used AP's own 5.1 that seems to work ok, was £4.50 for 500ml

Good luck

Tim
