I won't rub em against YOUR blacktop.  But seriously, go to any weekend track event and you will see guys doing just that. Sure, it's not pretty. And engineer types may cringe. But it does the job of removing glaze from the pad surface in a pinch, if you don't have sand paper around. I've seen it done many times and I've done it once.

What Kev said.
Minis don't drip oil.
They are marking their spot.
If it ain't leaking.
It's empty !!.

Geeeeeeez cheeeeeeezzzzzzzzzz ... Rub em against the blacktop isn't the kind of advice one should be giving out here, if you don't know any better, your best to keep hushed up. Anywho, it's probably a combination of sticking pistons and bad pad contact or materials. Take the calipers off and check the pistons move freely and are not rusty and sticking, you may as well go ahead and buy a rebuild seal and piston kit anyway while you have them apart, then look up "green stuff" brake pads, these have about the best co-efficiency of friction at low speeds for a road mini and will stop you on a dime even wehn wet if everything else is working correctly. Hell I ws out in mine in the rain just yesterday and had to stop hard, locked up all 4 wheels at 60mph in the pouring rain, that's almost as frightening in a mini as them NOT working, God bless ABS though not in this cars lifetime ...

I agree with pixieracing. It sounds like you have glazed your pads. Take em out, sand em with coarse paper or rub em against the blacktop. Reinstall. Wait for a rainy day. Prez, Mini Owners of America, Los Angeles

Rayman, Another possibility is sticking caliper pistons, if the pistons are sticking, the pad is only touching the disk when the pedal is pressed. The disk gets wet and when you apply the brakes, the pad has to wipe the disk dry first before the brakes will work (Its a scary place to find yourself!). There should be no clearance between the pad and disk so if you grab a pad and it rattles between the piston and the disk, you will want to investigate further to see if you need to get the calipers rebuilt. Cheers Kevin "Good ends, as I have frequently to point out, can be achieved only by the employment of appropriate means. The end cannot justify the means, for the simple and obvious reason that the means employed determine the nature of the ends produced." -- Aldous Huxley, "Ends and Means" 1938

the pads are too slick , with little use or hard pads they will becom very smooth , perfotrmance friction make a pad number 80 that works good in mini and stops good in the rain, you can always take the pads out and sand off the shinny part , put them back in a do a few hard stops for 60 or so , yiou may not have much brakes till the sanded parts seats which is usualy two or three stops.

I've driven my Mini for years without the rear dust shields without any problems in brake efficiency in the wet. Have you got really sports pads installed, that work best when warm/hard braking? Maybe try replacing them with standard cheapy pads, nothing fancy, and see how much difference it makes? Don't forget to put the clips back in when changing!  I didn't put mine in very well once, and the split pins wriggled out. On approaching a corner a big stone bounced round my wheel arch, clonking against the inner wing. Errrr... apart from it was one of the pads. Whoopsie!  www.MinisUnlimited.co.uk

well,
I was going to ask if you had brake shields, because their purpose is to keep the brakes dry. But you say that your brakes did this even with them on.
That would suggest that your pads are the issue. Pads are cheap, buy a reputable brand, and when you install them, put the shields back on, and see if that fixes it (it should).

I know this is a stupid question....but why do I have no brakes when I drive in the rain? I don't often drive in the rain, but the other day I did, and I forgot and almost put it in the ditch trying to stop. I am not sure what kind of disc brake pads are on it, but when they get wet, they don't do anything till you dry them out. Kinda scary driving with no brakes. It's got 8.4 disc and I removed the dust shields, (it did the same thing with the shields on) So could it be the type of brake pads? Anyone else have this problem?  If at first you don't succeed, redefine success.
