Gents,

I'm in the process of fitting new Mich PS4S tyres and Porterfield RS pads.

I've noticed a split in the rubber on the rear caliper piston dust cover.

Trying to find the part is becoming a PITA and I'm sure they're no more than 15 bucks a side.

I wonder if JLR share the F-Type brakes with say the X Type R or XJ or something similar that I can get a cheap replacement for?

Having had a prod around the existing dust cover, I feel it may be retained internally rather than the old fashion way of external bore fixing perhaps?

 

AFAICT the F-Type rear brake calipers (and pads), both the 326 mm and 376 mm versions, are unique to the F-Type.
Coz they have the EPB motor integrated with the caliper on each side and the other Jags which use these size brakes (eg XF, XJ) do not, they have a single central EPB motor which runs two cables, one to each side. The brake pistons are also different so I very much doubt if a piston seal /dust cover from a different model would fit/work on the F-Type.
But at least the rotors are identical across the various models!
I just had a squiz at my old 326 mm rear calipers and I would bet London to a brick that the piston dust covers are exactly the same on both the 326 mm and 376 mm brakes.
I'm fairly sure there are piston seal rebuild kits available for F-Type brakes for not a lot of $, I will have a search and report back.

Edit - that was quick and easy - this kit shows as fitting pretty much all F-Type brakes: https://www.ebay.com/itm/Centric-Rea...AAAOSw93xd0~e5

 

Thanks - I have dropped a line over to TRW (brake manufacturers) to see, but I'm sure they will only sell the cast iron caliper housings and not the seals separately.
I think it would be useful to have a set of part numbers handy as these are pretty much consumable items in my book.

There's not much in it, and the piston seals/dust cover will be common, but the housings I thinks are slightly different as TRW list them as (Choice of Red, Black or Silver in colour) and either 17'' or 19'' which I guess relates to the wheel size?

All said, it's still a PITA to renew the covers as they are fitted within the internal bore of the housing which means a strip down, remove the piston to fit.

For just over double the price of the kit you mentioned, i picked up a whole complete NOS OEM T2R7690!!! Crazy!

 

Yep, 17" = 326 mm rear brakes and 19" = 376 mm rear brakes.
Nothing to do with the actual diameters of the brake rotors as they are both well under 17" and 19" respectively, I can only guess they relate to the minimum size wheels which will fit over the rotors.

 

Well, I did some reverse engineering on the eBay add and chased the stock numbers to a company in Germany called ABS.
They make this rebuild kit that is common with the XJ and Audi A4, 5, 6, 7, 8, Q5/7 etc.

First inspection looks like it's all good quality and for only £5.25, an absolute bargain.
Of course most owners most probably won't need these 'till further down the line, when rubbers start to fail, but in case, here's a pic with all the relevant information on it for reference.
