Hi all,

Every time I start my car when cold, the brakes squeak when moving from park to reverse, and then into drive when pulling out of the garage. This only happens when my brakes are cold as once I drive around, the issue goes away.

I've recently replaced both my pads and rotors and this did not fix the issue. It was happening before, and now is happening after the install as well.

Any one else experiencing this? Any thoughts?

Thanks.

 

All three of my Jags (2010 XFS, 2010 XFR and 2014 F-Type) did this with OEM rotors and pads.
But more of a "graunch" than a squeak.
Swapping out the pads for ceramics (or Porterfield R4S on the F-Type) cured it every time.
What new pads have you got?
If it really is more of a high-pitched squeal then the best thing to try is to lube the pads with brake grease. Ceramic based high-temp stuff, smear it on the packs of the pads and on the ends where the pads touch the calipers.

 

I installed Porterfield R4S as well! It cured it for like a day and then came back. A "graunch" may be a better way to describe it as opposed to high pitched squeek. I'll try to take a video. I lubed the pads big time as I know that this sort of noise can result from improperly lubed pads, but apparently, it didn't help either.

I'm wondering if the pads are glazed over and need bedding? I've got about 150 miles on them now and I did not bed them at all. Did you bed yours a certain way?

 

It does sound as though you have glazed pads.
Yep, I bedded the new Porterfield R4S pads.
Eight or ten heavy brake applications from around 60 mph down to around 10 mph (don't stop!) in the space of a couple of minutes, until you can smell the pads.
Obviously you need a reasonable long quiet stretch of road to do this.
And again, do not stop the car once the brakes have got good and hot (and hopefully bedded in!), instead go for a gentle cruise or "cool down lap".
If you stop with really hot brakes and pads you risk "imprinting" the rotors with pad material (AKA pad material deposition), then you will need to get the rotors machined to fix it.

 

Ugh. I always have a buddy bed the pads for me since I get quite nauseous when doing so. I didn't do so this time, so let's see if that helps. Thanks for the suggestions.

 

Yep, same here with the nausea every time I do this, but as they say no pain no gain!

 

When my wife complains about the low-speed squeal, I tell her

"That's how you know the brakes are working"

 

I have not experienced this but I wonder if this is related to the rear parking brake just releasing after being engaged when in park. It would help if we can determine if it's from the rear brakes

 

Mine were groany and squealy after sitting overnight especially after I put the new wheels on (dont understand the corelation) but that improved enormously after it was serviced and the service guys cleaned them up

 

With the stock rotors and pads I had this quite a lot, and still had it with Centric Posiquiet semi-metallic pads.
Once I fitted the slotted and drilled rotors off the old XFR and the Porterfield R4S pads I no longer had this noise.
That said, the rear parking brake is only one part of the "graunch" problem, I found that the front brakes made more of the noise than the rear brakes and the brake specialist I used to go to reckons that some "graunch" is normal for big floating caliper dual piston brakes like the 380 mm ones on the F-Type.

 

My buddy is going to bed the pads tonight for me... Will circle back! I'm not terribly optimistic given that my old pads did the same thing so we'll see.

 

I have 3 F-type in the shop right now. I purposely had someone else reverse the car so I could be outside and I still cannot hear this noise.One even has EBC YellowStuff pads (known for noise)
