Brake drying

[Finglonga]

Or maybe there is an advantage in having brakes drying themselves when they are wet?  Ready for sudden use?

Yes there is, you go through a flood and then try to stop without is you realise what it is doing. Years ago after floods there was the Try Your Brakes signs, they are not needed today because of the brake drying on modern cars. You can set the severity of how it dries them with OBD11, but the standard setting is fine.

It's a standard feature on the mk7 GTi so no need to do anything with obd11

Thank god this is standard, I've been worrying about this for years in case I need to stop when its raining.....

Now I thought that sign was for drum brakes, because the water can sit in the drums

I wish they’d invent something so that after you’ve washed your car and put it in the garage, the brakes don’t seize on. Several times I’ve Tried to reverse out a few days later only to not move, then suddenly after a loud clonk everything frees up. In sure I knackered the rear pads on the A3 the same way, fortunately replaced under warranty. It’s even worse if there’s an overnight frost. If my car has wet wheels I tend to just leave it in P and not apply the parking brake anymore.

There you go, you've invented it yourself.

Kind of. But it’s a pain in the ass when you forget Auto Hold is switched on, which applies the parking brake automatically when you switch off the ignition. Then you have to switch it on again just to release the brake. Not a problem on old school cars, but I’m not keen firing up all the computers/virtual dash unnecessarily, given I have a glitch where the virtual dash stays illuminated for half an hour unless the engine is also started. Yeah I could take it to VW - but they probably won’t find a fault. And if they do, they’ll want the car for ages or I’ll have to spend hours messing around waiting. 🤷‍♂️

This is a new one on me tbh. Never even knew this was a thing. As they say you learn something new everyday.

Yes, I know what you mean. It happens on pretty much every car, plus the rusted discs turn to orange dust as soon as you drive somewhere so you find the wheels get dirty quickly.

I've found that running the car forward and backwards a few times can help and using an air dryer to dry the wheels and brakes is best but like you say, leaving the parking brake off is the best bet as if they are wet and it's cold they cold with a real clunk when stuck on which can't be good long term for the discs.

The bit that worries me is when it leaves part of the pads on the disc. This thing needs a VW solution, really, as once this happens the damage speeds up. Quite a number of people on here have had to replace rear discs and pads at silly low mileage.

The rear brakes are responsible for the adaptive cruise control and hence wear out quite quickly if you’re a fan of that.
Mine will need replacing at about 23,000 miles.

I didn’t realise that. It explains why ACC braking felt odd but I couldn’t quite put my finger on why. Does anyone know if the rear brake lights are engaged when this happens? The braking is almost like lifting off the throttle rather than applying the brake.
