Maybe I should have read the manual ... But I didn't expect this ...

Took the TTS through a touch less carwash to rid the salt ... It also rid me of all stopping power!

Very thankful there was no one ahead of me coming up to the first traffic light out of the car wash. Otherwise it would not have ended well.

It took about a mile of occasional break pressure before it was back to normal.

Initial Google searches on this are not conclusive ... Hand washing only with no soap on the PCCB?

Rain will do the same for the first block. It's very disconcerting until you get used to the fact that you need to pump the brakes a few times to dry them off. How you wash it will not matter in my experience; when they are wet they need to heat up just a bit.

i drive my car in the rain alot ... with no ISSUE at all !!!!

NO issue with mine either. Perfect in the wet. Interestingly, my salesman told me wet performance was better with PCCB.

I did my first wash yesterday and I noticed the same thing - there was a much greater reduction in braking effectiveness immediately post-wash than I was accustomed to with iron brakes. Seemed to recover quickly on it's own, though.

I'm no expert in PCCBs, but were your car's brakes relatively hot when you got them washed? Maybe that helped cake a coating of soap (or something else) over it? I think I had read somewhere that getting your car washed when the brakes are hot can be damaging to the rotors... just trying to think a little outside the box here.

But dang, that is concerning if braking ability is hampered that much in the wet...?

I had just exited from the freeway ... But outside temperature was about 20F.

That touchless system is probably blasting the wheels and rotors with soap and wax and everything else then water ... Next wash will be with coin op and I won't get much but a bit of water in there and will compare then.

Thanks for the input.

This is a well known issue with PCCB and discussed many times on this forum. I only experience it with the discs cold and immediately after the car wash or a soaking rain if the car has been sitting out. I assure you this has been described numerous times.

Didn't expect I was the first by any means ... But this almost rises to level of needing a bright yellow warning label on the visor ...I am just a PCCB newbie ...
