So I just changed all brake pads and all 4 rotors. Now I notice a clicking noise coming from what sounds like the front brakes. Any ideas what the problem could be?

 

Figure which side and rectify whatever's wrong. Gonna have to take it apart again...

 

Think it could be loose bolts in the caliper?

 

Only way to know is take apart & check. Did you tighten them? You'll have to check because you could be wrong.

No, I don't think it'll be bolts because I GUESS they wouldn't click. Guess isn't good enough for safety systems...

 

One possible cause is improperly-seated new brake pads that are now contacting the rotor surface at all times. A very common mistake regardless of the type of vehicle. I made that mistake decades ago and it taught me to triple-check the new pad position before reassembling the calipers....

 

Did you install the anti-rattle shims on the new pads?

 

Thanks for the replies. Yes I installed all the shims and I also notice I hear the sound when going over bumps.. Tuesday I will take it all apart and re assemble.. I'll report back then

 

Check and see if the pads are moving up and down in the caliper holder. Often times with cheaper aftermarket pads, the mold used is slightly off and the pad comes out smaller and rattles up and down even with the proper hardware installed.

 

Found out today it was one of the sliding pins.. It was siezed. I sprayed wd 40. And reassembled the sound was still there for a while but has seemed to vanish after about 10 minutes of driving. The mechanic I had inspect it wanted 80.00 to removed the pin and clean ,grease and re install. I declined. But it seems wd40 has solved the issue. Hopefully it won't return

 

WD40 is not a permanent fix nor even a good temporary one. The pins should be removed, cleaned and regreased at each pad swap.

 

The problem is the pin would not come out.. When I changed the brakes/calipers I removed what I believe to be the pins( the bolts) and put anti sieze on them. Maybe I should not have used anti sieze? Maybe those weren't the pins?

 

The pins allow the caliper to slide laterally as the pads wear. If they seize, the pad on the outside of the rotor will gradually loose contact with the friction surface and become ineffective.

 

Purchase a small tube of caliper pin synthetic grease at any auto parts store. That is indeed the most appropriate lubricant for these sliding caliper pins. Use it very sparingly to avoid greasy build-up. One tube will probably last you for many years....

 

aaah,,, pins is pins,, bolts is bolts

If the calipers are similar to those on other Jaguars, the caliper bracket is held to the suspension by bolts and the caliper is held to the bracket by the pins. The caliper is normally removed by unscrewing the pins, but can be removed by removing the bolts.

The problem is that all of the floating motion is in the pin. Therefore, the pins have to be removed and polished up or replaced. The silicone based brake grease is a must on every service.

The only possible butchery you could perform is to take it apart again at the bolts leaving the pins in, polish the pins, lubricate the pins with brake grease and put it back together. It'll work, but it's a hack job.
