Hello everyone first time posting a question here, but have lurked the forums for a long time.
I have a 2002 F250 Lariat CCSB 5.4l.
let me start at the beginning,
My truck started to develop a shake in the dash and steering wheel a while ago. It would be worse some days but not as bad depending on how much I used my brakes. As soon as I would put pressure my brake pedal the dash would shake violently and my steering wheel would wobble. So I researched for a long time and found it was more likely to be bad "warped" rotors with hot spots on them causing the pads to grab better in some spots. I didn't think it would be ball joints because it would shake only during braking, I don't have any shake or wobbles any other time. My tires have about 20k on them balanced perfect and I have them rotated every oil change because they are a little more beefy than stock and I drive highway to and from work everyday.
So I pulled the wheels off and checked everything and they looked alright, pads looked ok, rotors seemed fine for an older, high mileage truck nothing noticeable. So I pushed the caliper piston back in a little to get them back together and decided to just go ahead and purchase new front rotors and pads just because I figured it could only help.
When I decided to replace the parts this past Sunday everything went smoothly nothing was to difficult to do and I didn't have any trouble getting the calipers off and brackets off. I greased the slide pins as the didn't slide that smooth, and pushed in the caliper piston (It did feel slightly tougher than what it should) replaced the rotors and pads, torqued everything to spec. Then put the wheels on and torqued those to spec and went to go and bed in the new rotors and pads.
Got out on the road and still had a bad shake/pulse in the steering wheel and pedal! I was stumped, so I did a 35 to 5-10 mild braking with a few 50 to 5-10 harder braking but still had the shake and pulse.
So I got home went inside to think and research for a while then decide to pull the rears off and check those out since it felt like the pulsating may be coming from the rear from the way the truck would slow down.
Got the rear wheels off and noticed the rotors were in tough shape. Tried pulling the calipers off, after a few hours of fighting each side I was able to free the calipers. Found out each caliper has a stuck piston, along with bad looking rotors, cracked and breaking pads. So I figured this is probably causing some problems haha.
So yesterday I bought all new rear rotors, calipers and pads and was ready to get the pulse out of my life!
Pulled everything apart, adjusted the emergency brake to make sure that would grab, put rotors on, put brackets on, put the new caliper on, then I bled the calipers until I felt they were good to go.
Took the truck for a drive.......and same damn thing, better stopping that's for sure, but still have a pulse and steering wheel shake. I also noticed a grinding noise in the front like a pad was just riding the rotor. So that leads me to believe those pistons on the front need a rebuild.
At this point I am going to rebuild the front calipers since the weren't completely stuck (and a o ring and dust boot are $7.99) to hopefully fix this issue.
Otherwise i'm all out of ideas, and money for now :laugh2:
any thoughts/help/conversation would be greatly appreciated. Thanks!
