Brakes squealing loudly after cleaning with CRC Brakleen! Help!

Hi
My brakes were making light noise and I found that the brake pads were OK. So I bought CRC Brakleen from Walmart and sprayed the brake assembly (without removing the callipers). I sprayed quite a bit as recommended. I collected the blackish drain-off at the bottom.

After putiing back the wheel, I tried to use the brake and it is now making pretty loud squealing, squeaking noise!!! It almost feels like metal scraping against metal. I did not touch anything else and I dont know what went wrong? Did I use too much of the CRC Brakleen fluid and end up damaging something else?

Any suggestions on what to do next? PLEASE HELP!!!!

Thanks in advance
Vijay

No it's fine.
I would take the wheel back off & check the pads against the metal warning squeeler.

Thank you so much for the advice!
I had not inspected the brake pads properly. When I opened the calipers and checked the pads, they were totally worn out!
When I had used CRC Brakleen, I had removed all the grease and that is why it was squealing\squeaking so badly. Thank god for that. Otherwise I would have thought that the pads were ok.

BTW, the instructions with pictures for brake pad replacement are excellent here-
