Crunching Noise when stopping, Clicking when rolling slow

If there's no warning lights on, and the brakes are working properly. I would make the drive home and then try to determine what's causing the sound.

 

If you have insurance, or AAA like coverage then I don't think a tow truck usually costs that much.

From other posts, and other happenings, the damage that might be prevented can often make the expense well worth it.
Not to mention, IMO the most important aspect which is safety.

Worst case scenario? You pay for a Tow Truck, go through the hassle of waiting for it, and having your vehicle towed, and discover the problem was very, very minor, and you could of driven it safely. Net Loss...a little time, a little money.

If the problem is more serious, or the type of problem that can be worsened by further driving? And given that it's seems to either be brake or transmission related, NOT towing could result in a much worse outcome. Including a safety risk.

I could be totally wrong...but in this case, I'm willing to be wrong. I'd call a tow truck.

 

sounds like something was caught in the caliper, and now it has been reduced to a minor annoyance. jack it up and spin the from tyres. if no odd sounds or feel, pull the tyres off and inspect the calipers and pads.

 

regen takes place inside the transmission. wheels/brakes, hubs/axles same as any car. all the best!

 

i hope not. don't recall anyone complaining about tranny noises.

otoh, if you intend to keep it for awhile, a salvaged tranny is cheap, and not too bad to install.
