New Rotors - vented or unvented

Hi
Not strictly for my my Rover, but my 5 year old Jaguar XE which has heavily scored rear discs. I am thinking of embarking on the job and wondered about the choice of discs that are available , vented or solid. I am light footed on the brakes and a low mileage driver on both the Rover and Jaguar. Most cars I've owned have suffered scoring and I believe it's a result of low mileage and light braking. I've only covered 21000 miles in the Jaguar and understand that vented discs dispel water quicker, which may help with rusting. Your thoughts and any links to suppliers of good quality mid range discs.
Thanks:shrug:

have a look here, might help, and it will show you whether they are vented or not

The discs on all my cars are from them, and highly recommended that you get them coated, that way they still look good behind the wheels for quite a while, and not ugly rusted discs

Vented or unvented would be dictated by the caliper fitted surely.

What is the coating like?
I see they offer black edition coating, is the disc actually colored black?

The disc’s on the front of my diesel we’re coated white?? You don’t need to clean it off, and now, three years later, they still look like new when seen through the wheel. I think they were Pagid. The disc’s are smooth on the surface even after around 20,000 miles, and they have never gone rusty even though it has been in the garage for 12 months because I have been using the 2.5 Connie.

Black when you receive them but the colour rubs off in use on the contact areas.

Short answer is you should fit like for like.

I think you're confusing vented for drilled / slotted discs. Vented will not dispel water quicker then solid however drilled will do. You'd probably (although not always) have to replace the callipers to go from solid to vented however you can go to drilled without any other changes.
I have upgraded to slotted / drilled discs on cars I use on track however I'm not sure it made a huge difference but it will cause more wear on your brake pads so unless you're doing lots of performance driving I wouldn't bother.

Hi Rob,

As you have scored rear discs as opposed to surface rust I'd say it has nothing to do with your mileage or light braking. Scoring must be the result of abrasive contamination so try more frequent maintenance. Remember that on all cars the rear brakes receive reduced fluid pressure anyway no matter how you press the pedal.

Simon ;)

oh and a discussion with your insurance company should take place.
