Brembo Caliper Repair Kits - Out of stock for months
Looks like the dust boots on my Brembo 4-pot (grey, 40 mm) calipers are starting to die. They looked a bit 'cooked' but no holes yet.
I've been searching around for a repair kit by either Brembo or Centric. Have found kits on Ebay but by manufacturers I have no idea regarding quality. Anyone have a lead on where to get either Brembo or Centric Caliper Repair kits?

I did give him a try and he mentioned he hasn't seen any of these parts for months. What on earth is going on with the supply chain these days?

I love RockAuto but in this case it's hard to tell if the kits being sold are the right size. Seems some details are missing.

Difference now is that press isn't covering Covid, few people are wearing masks and new variants aren't stopped by blue or yellow surgical masks, only N95/KN95 masks work against new variants. |

Rockauto is the spot. Blue (340 Msport or 370 m performance), red|yellow| orange (mperformance 370), Grey 4pots and f8x 4pot only differ by the paint. They are all 40mm pistons. The 2pot rears will be 40mm (f3x f2x) or 44mm(f8x) pistons.
So all of those "rear w/ blue caliper" are all 40mm. The front kits with seals for 4 piston are all 40mm. The first one is a kit with one seal so it's for the sliding 1pot that comes with the Grey 4pots. All 6cyl f3x Come with 4pot up front. Just did a full rebuild on 340mm greys and m235 2 pòt rears and powder winter 2020. You can even use the part numbers to buy them from other places.

You're looking for Brembo PN 20.4872.46.
I found this place listing 19 in stock (you need 8): https://addictionmotorsport.co.uk/du...-seal-20487246 They're available from many places. Google is your friend.

A little pricey too. 11 GBP is 13 USD x 4 per caliper makes just the dust seal $52 per caliper alone, without the inner square cut seal for the inside of the piston. Typically a kit of dust and square cut seals is USD $22 per side for a name brand, less for some of the cheaper stuff (see posting referring to Rock Auto). I generally tend to stick to BMW or OE (i.e. a brand whore) so I don't mind paying a bit extra but for a full kit of dust and inner square cut seals, a 400% markup seems a tad pricey in this case.

I love Rock Auto but while I would pick Centric for brake parts haven't much experience with Raybestos or AC Delco. How could they screw up a seal? Do I want to find out? Do you have any experience with Raybestos or AC Delco? Maybe it's a given that if the car is tracked, those seals are like spark plugs, replaced once a year so any brand chosen just needs to hold on that long.

That's the correct Brembo part number for the 4-piston front calipers. The F3x (and probably many others) cars use Brembo calipers. The manufacturer's name is cast in the back (please see the above caliper pictures).

There's always 3rd-party parts from Rock Auto and other similar places.

I got my rebuild pieces from Patrick McC at lbhsbz@hotmail.com. His kits include the piston boot/seal, the crossover seal and some assembly oil. Send him the Centric part #s and he should be able to source them for you: Front: 143.34039 Rear: 143.34040 Probably around ~$25/corner + shipping from Cali.

Rock auto has all the parts you need as stated already. I've had the AC Delco, Brembo, and Raybestos in hand simultaneously and you will be fine with either. I currently have all three installed mix and match to make a full set.
