2003 Civic Si - Weird Braking Issue
I just bought a 2003 Civic Si. Two days after driving it off the lot I noticed a weird knocking sound while braking. Upon further investigation I noticed that when I brake lightly (while downshifting), the brakes make a knocking noise. However, when I brake hard with no downshift, they work fine and there is no knock at all.
I took the car to Midas. They told me there was some rusting on the rotors and drums, so they cleaned and adjusted the brakes for me.
Now the problem is even more pronounced, and I can hear the knocking even louder. I called the guy from Midas back and told him what was happening, and he said it's normal.
In my entire life, I have never ever heard brakes make a knocking noise while lightly braking, yet work fine while braking hard.
It is stressing me out because it feels like there are some loose parts or something, and I don't want to be on the hook for a huge repair...
Would a slightly warped rotor cause something like this to happen?
