Ok so here is the deal. its a 2002 wrx 68xxx miles.
1)Recently I've been having a problem with my brakes squeeling when slowing down so i decided to install new pads all around and this fixed the squealing problem. Well not untill today ( this has been about a week now) have i actually had to hit the brakes hard. I noticed the brake peddle was stiffer but today on the highway i got cut off and i slammed the brakes and it sounded like a grinding sound. I was wondering if this is just the coating on the new pads coming off or if its something i have to worry about. It just didn't feel right.
2) i took my car to a local shop and to get a tranny flush and a oil change. they put mobil 1 synthetic blend in it and some coastal 75w-90 gear oil that sounded generic and not something i wanted in my tranny. So after a month or so i decided me and a buddy were going to change the oil and fluid again with stuff thats good ( i heard mobil 1 is terrible for these cars)
So we changed the oil and the tranny fluid and when we went to check the levels it was hard to read the oil( valvoline synthetic) but it seemed to be on the high side and when we checked the tranny fluid it was way over the full line( royal purple 75w-90) so i was wondering will this affect my car in anyway negativly for atleast the next 3k miles when i want to get them both changed again with the correct ammounts
