It is getting time for me to do the brakes on my car, and while I still haven't figured out if im going to stick with factory pads/rotors or go aftermarket, I do know I want to replace the 10+ year old rubber brake lines, but I cant find any stainless lines for the 03-up normally aspirated. I have found sets for the 99-02 and all STRs. Does anyone know where to find any, or if the ones for the other models work? If all else fails I will just get some stock ones from the dealer, but this is one of those "while im in there upgrades." Any info is greatly appreciated!

I know the STR has SS lines stock but I was not sure if the rest of the S Types did?

Some people mistake the factory ones on the STR because they don't look like the aftermarket SS ones and have a black plastic covering on them.

Hi PerrysJag, have a look on Ebay or contact sellers of Goodridge brake hoses.

My 2004 4.2V8 has factory stainless brake lines.

You sure?

I would have to get my car up in the air again and check, but I'm pretty sure they are just standard rubber. I asked parts when I worked at the dealer and they couldn't tell me

I don't wish to be a pedant but:

1.I am sure my car has SS brake lines.

2.I cannot verify that they were installed at the Jaguar assembly plant(I was not present at the time).

I have owned the car for about 7 months,every part I have looked at on the car is Jaguar--even the battery is Jaguar(made by Varta in Germany).
It is possible that someone changed the brake lines/hoses.I have attached pics so you may judge for yourself.

I think you may be right. I put my car in the air today and looked at them again. They seem to be hard, but not like hard rubber, with a plastic shield over them. Only way to be for absolute sure is to dissect them off the car. I figured they were just rubber, my brakes are quite mushy and I know rubber lines will cause that issue. I may be looking and another problem

For what it's worth, I have an 06 4.2S NA with a late VIN number.
These and later models came with a Teves braking system; larger
disks, different calipers, pads, etc. They also came with stainless
steel flexible brake lines. I have no idea if you could retrofit these
lines to your earlier calipers; might be worth a try.

They're all Teves I think. I'm less than convinced about the disc size...

My 04 V8 Sport has the stainless brake hoses with 320mm discs up front.
Don't know when the stainless hoses became standard though.

I did rear brakes on a 2000 the other day, and they are for sure standard rubber lines. And yesterday I took all the wheels off my car to flush the brake lines and I am confident they are stainless lines. They have a clear plastic shield over the top. They were just so dirty they looked black! I guess I should have looked before. But must be Jaguar started SS lines in 03 on the S-Type

320mm are smaller than some of the other S-Types (326mm, mine being 365mm).
