Re: Brake pad problem
First remove the caliper, held by two bolts. Make sure you support it when removed - do not hang it by the brake hose. With the caliper off, you can remove the sled holding the pads. It's also held by two bolts. With the sled off, the pads pop right out of their slots.

There should be an adjustment to take up the slack in the parking brake cable. Although, If the brakes were properly serviced, there should not be any looseness in the brake pads. There are sprays and stick on pads that go on the back of brake pads to prevent rattles and squeaking. It would necessitate removing the brake caliper and brake pads. Personally, I would take it back to the shop that did the job and make them fix it. New pads should not rattle.
Are the leading edges on the brake pads bevelled at an angle or are they flat on the brake rotors? There seems to be a problem with Japanese brake rotors (something about the harmonics) and they will sometimes squeal (even with new brake rotors and pads) if the leading edges on the brake pads are not bevelled at an angle. Most of the auto repair shops that I have worked at will only install bevelled edge brake pads on foreign vehicles, especially if they are Japanese imports. If the brake pads do have the edges bevelled then most likely dust has found its way between the brake pad and the brake rotor, and brake dust contamination is the #1 reason for a brake squeal come-back, and that is why a good repair facility will always clean the entire brake assembly including the backing plate for the brake rotor. Also, the brake caliper guides should be able to slide freely in and out of the brake caliper but they should not be sloppy either, and the brake caliper guides should be lubricated with a synthetic brake caliper grease only. The caliper guides should be able to slide freely in the brake caliper and if they do not the brake will not properly release.
If the brake calipers have phenolic (plastic) brake pistons then get rid of them for brake calipers with metal brake pistons.
Here is an image of the two different brake pad designs.
THE LIGHT FOR THE PARKING BRAKE IS SOMETIMES ALSO USED FOR LOW BRAKE FLUID LEVEL OR WORN OUT BRAKE PADS. CHECK THE BRAKE FLUID LEVEL, A FLOAT ACTIVATES A SWITCH WHEN THE LEVEL IS LOW. IF THE LEVEL IS VERY LOW BUT THERE DOES NOT SEEM TO BE A LEAK, CHECK THE CONDITION OF THE BRAKE PADS (FRONT & REAR). WHEN THE BRAKE PADS WEAR OVER TIME, BRAKE FLUID REMAINS IN THE CALIPERS TO COMPENSATE FOR MATERIAL WORN OFF. ALSO A SMALL METAL CONTACT EMBEDED IN THE BRAKE MATERIAL WIRED TO THE PARKING BRAKE LAMP, WILL MAKE CONTACT WITH THE DISC (GROUND) WHEN BRAKE PAD MATERIAL WEARS OFF AND LIGHTS THE LAMP.
For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!! For front brake pads. First you must verify yours front brake disc diameter: 280 mm or 288 mm. (On my car y have 288 mm). After that you can buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow: 1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose! 2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper. 3. Now you must thoroughly clean the brake calipers (free of grease). 4. Remove outer brake pad from brake carrier. 5. Pull inner brake pad out of brake caliper piston. 6. Check up the brake fluid level on the reservor, and emptying if neccessary! 7. Push piston back into brake caliper housing. 8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward). 9. Install outer brake pad into brake carrier. 10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm. 11. Install both caps. 12. Insert retaining spring into brake caliper housing. Important: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!! Check brake fluid level and top up if neccessary!!!
I fill you in what I learned today. I have a 2005 S-Type Jaguar and the dealer sayed it needed new pads in the rear. They wanted $300 just for the pads and another $150 or so to install. That $450 bucks to replace the brake pads only on the rear of the car. And of course, the extended warranty doesn't cover this, so I said no thanks. I found the best brake pads from Napa for $52. I purchased them through my brothers shop- saved a little. I done lots of brake pad replacements over the years, but not on a new car like the Jaguar. Well they are a little different and the frist one took me awhile . Here is the trick. 1) MAke sure the parking brake is off and you do this by starting the car, stepping on the normal brake and then pushing the parking break lever down while shutting off the car. 2) You then take the tire off, use jack stands to ensure safety.3) Take off brake callipers, 2 bolts and the brake pads should just fall off.4) take the anti-rattle plate off the old pads by prying it off carefully with a tiny screw driver- clean and then install on the new ones. 5) Here I release the the valve for the brake fluid. I did not want to damage the system if the fluid went back into the system when I retracted the calliper. You use some fluid, but you can add when finished. 6)You either need one of those brake calliper tools that you push the calliper in with and If you don't have the trick new one with the keys to turn the brake calliper cylinder, you can get by with the old version like I did and use a pair of channel locks to turn counter clockwise, while continuing to turn the tool. The cylinder needss pressure on it while you turn. This will put in in the proper place. 7) Ensure you have the slots up and down so that the pin in the pad fits up into the cylinder. you know this is correct when you have it perfect vertical and center within the calliper. Pay attention when taking off! 8) Set the brake pads in their proper place and then slide the calliper over them. IT should go over freely or else you need to turn more on the cylinder. 9) Tighten the bolts and replace the tire and you are done. Next side!

Contact your dealer soon, some of you people are going to get a campaign and the others must complain to get the updated pads to reduce the brake noises. Seems like they are eliminating some of the brake pads to make this happen. Instead of 4 small pads there are two large pads per caliper.
