Hi guys,

Been trying to figure this out for ages, and asked around and couldn't really solve it.. and im desperate to get rid of it..

both the disc brakes ive had on the car, have made clicking noises when i move around in car parks, or driveways at low speeds back and forwards.

It has been tracked to the pads themselves moving within the caliper and making a clicking noise as they hit the caliper either way the car moves.. I must say this is BLOODY annoying as you can here it at low speeds, and when you apply the brakes, and I want to get rid of it..

first i thought it was due to maybe after market calipers, but I am sure I had genuine ones before that, and they still made that noise,

I thought if i just got the genuie caliper, then I would have solved this problem, due to the after market one being cheap nasty casting or something,

BUT the idea of a restricting value in the MC has been brought up by one of our lovely members here and I/we are wondering if this is causing it?

There's something wrong somewhere and its damn annoying I must say..

I have an awesome pedal for brakes, its like having ABS but in a mini.. so nothing wrong with the brakes, they work GREAT!

Any ideas would be much appreciated.

Thanks Lockie.

If your mini feels like its got ABS you have a big problem Have you ever had to use the abs on a modern car , it feels bloody awfull

ask yourself why the pads would be able to move around in the calipers... it'd mean the pads and rotor are getting an air gap = warped rotors

ditto to mini maxx - if it feels like ABS, then same thing - warped rotors

Have you got the lil plates behind the pads?( anti squeel plates i think) I did notice when i changed mine that the pads were "glued to the lil plates and they were in turn glued to the caliper pistons with some sort of orange goo ( excuse my vagueness) Are the 2 split pins the right size?

Lockie do you mean the pads are hitting the calipers on forward /reverse rotations (moving from top to bottom of the caliper) not in and out as the wheel rotates ( being pushed in and out by the disc)??

precisely mate

my x-trail rear discs used to do that.. I fixed it by using some of that orange anti-squeel stuff maxx mentioned above, seems to hold everything together and stopped the clicking...

'a mini is for life, not just for christmas!'

Is it really the calipers?

There are a lot of other spinning parts down there.

my deluxe did this. It was the anti squeel plates or whatever they are, moving side to side and touching the rotor.

I know what you mean about the pads moving, however I've only seen it so far in motorbikes. You only hear it as the bike pulls up and relaxes back a little, or vice-versa... click-click as 4 pads all settle back and forth (not side to side) into the caliper.
The brake pads in your discs shouldn't really have that much movement however.

yeah this is what it is like....

it just seems that the pads themselves have too bigger holes where the split pins go, and the split pin is as big as you can go to be able to get it through the hole of the caliper.... so to me it seems a catch 22, but i also don't think the spilt pins shouldnt be taking all that pressure of the pads moving on hard braking should they?

I would have thought they would brake? They are there just to really locate them and keep them in place right?

The split pins bear no mechanical load, or at least if you want to live very long then they shouldn't. They just stop the pads working in an out too of the caliper. its like holding your dog's walking lead while it cheeses a nard out on someone else's driveway. You're not actually doing any work, you're just making sure its not doing it in your yard.

The load will be absorbed by the caliper, as it was always that way anway, but just make sure that it is the pads for certain and not something else first.

Get someone to sit in the car while you have it off and up on axle stands. have them touch the brakes enough to just grasp the disc and move the wheel back and forth. You should be able to see the pads moving and hear them click if the problem is as you have described.

yea that's what I thought, i couldn't imagine the split pins doing the work..


Yep have done this already, and it is definitely the pads moving and hitting either side of the caliper.... I really don't know why this is happening, I know i could maybe put some sort of silicon on the caliper to stop me hearing that noise, but even so no one else brakes do this.. and this is what concerns me... I'd like to fix it properly really..

Don't touch it if it is. Its just the way it is. You can't add anything to the calipers to improve the condition lest it interfere with the way it functions.

It might be the copy calipers, or it might be the pads are a little narrow, or both. measure the pad width and compare against another set to be sure.

hmmm, if I can get hold of another set of disc's not exactly easy. Most people I know have drums..

What makes me wonder tho, the disc's I had on there before the ones I have now, also made this noise, the my mate who has them now, says they don't make that clicking noise,, so that makes me wonder it's something to do with my car?
