stalled while driving

What kind of petrol is best for my car? Leaded or unleaded?

Do you have a cat converter fitted? unleaded with upper cylinder lube should be fine.

I've been trying to find the problem with the front end of my pickup.
The problem is a rattle that goes away when the brake pedal is depressed. I was told that it may be a suspension problem, so I replaced the sway bar bushings, the sway bar end links, and the struts.
Last Sunday, I replaced the brake rotors and pads. The rattle went away until Friday, and I heard a faint sound of the rattle again, and it has gotten worse since.

i would look at the pad mountings and make sure they are tight in there mounts.
