First of all these series of calipers are so easy to change out, this one came pretty quick even though I wasn't in a hurry to get it. Quality seems good but one thing that I did notice is it got rusty really easy, I put in on my truck and a few days later when I went to bleed them I noticed it started getting rusty and I haven't even driven it yet. Maybe it's the PA weather but I figured the paint on it would last a little longer. Not a big deal as it's not a show truck. Works good so far and priced right. Would recommend them!
