My XKR Brembo brakes squeak and squeal like crazy and to be honest they are driving me crazy. I've tried all kinds of pad brands to no avail. I've been looking at the exploded diagrams and came across the fitting kit. In that kit there are some small 'bits' ; I don't know what they are but I don't think I have them in my setup. Could those be my saviour.

The bits I don't have are in the picture and are just above the 'R' Clips and below the anti rattle plate - what are they and do I need them, and, will they stop my squeak?

 

I believe these bits are what the sides of the pads backing plate slide on. Nothing good would come out of cheap steel backing plates rubbing against expensive aluminum calipers. Some have reported these bits need some form of greasing to quiet some of the noise. From memory, the bits I have seen screw into the caliper body in the general vicinity of the pistons, and are sort of L shaped. Hard to believe you do not have them already.

Have you tried the red goopy product typically used for these noises? It is typically applied on the back of the pads, where the pistons apply pressure.

Best of luck, keep us posted.

 

I think your Brembos will be almost the same as those on my 2004 STR.

It only has the large metal spring clip and the 2 long pins. I've never seen the other 4 small items! (And they appear unnecessary.)

 

Those parts in the picture are for the TOP of the brake pads, the two retaining pins, 'R' clips and spring pad. The two smaller pieces normally fit on top and bottom of the pads where they slide into the caliper itself and stop them clicking when braking.
They make up any shortfall of pad length on the metal section of the brake pad itself.
Your brake pads will have a metal backing plate on them, near enough the full length of the pad.
Use some copper grease, put a light smear all over the backing plate, that will normally stop the squealing.
I'll see if I can find a better diagram of the small bits in situ.

 

I can't find a brembo fitting kit that has the little guide plates included.
Apparently the jag number 1130985 says they are something to do with abs accessory kit.
It is quite possible that you may not have or need them.
But they are cheap so I'd grab some anyway.
Then strip the pads out again and have a good look.

Odd that mine didn't have (or apparently need) them.

 

This is the front RH Brembo on my 2005 XK8 4.2-S:



Pins and spring retaining clips ('R' Clips - arrowed) but not the 'spacers' shown in your illustration.

Although they do appear in the JEPC illustration, they weren't in the Brake Pad Pin/Clip (JLM21320) Kit I ordered from Jaguar at the time nor is there any reference to them in the JTIS pad replacement procedure.

Note there is no mention in the text nor are they shown in the diagram.

To the original question: no the spring clip probably won't fix the squeal. The solution is to grease them well between the pad and caliper.

Greasing between the pad and rotor would also solve the squeal but may have undesirable side effects.

 

Loud squeal from driver and any passengers!!
