Brakes Feel Strange

[Toyota3000]

Hi all

Is there a reason why the brakes feel really rough when the car's not been driven for about 24 hours ? - it feels as if the auto-braking system comes on, even if the road is absolutely dry.

I can understand the auto system coming on when it's icy etc... but not otherwise

Is there a problem somewhere ?

Thanks in advance.

Could be surface rust on the brake disk that's built up if the car hasn't been driven for a little while - especially if its been left outside in the rain or after its been washed...

The first few uses of the brakes will be a bit rough (and "grabby") if that's the case until the disk cleans itself up again...

Thanks, alfiejts.

The thing is, everything's fine a few minutes later; I'm surprised how much effect 24 hrs can do, even when the weather's been pleasant.

Also want to add that this seems to be a recent occurrence. Do you think the brakes (or brake pads) could be worn ?

Yeah, surface rust, forget 24 hours! See what happens in a few minutes when water touches the discs!
