I replaced my warped front brake rotors a couple thousand miles ago and all was fine but when I went to swap over to my snow tires, I can see that the outer part of the rotor has been rubbing on the caliper bracket. This is happening on both front rotors. Could my new rotors be too thick or something?
View 4 RepliesI'm working on a 2007 Camry and I had the wheel bearings pressed in & out at a shop. I put everything back together but the driver side rotor is rubbing against the caliper bracket. And there is no air gap between the rotor and bracket so it can spin freely without rubbing. The passenger side is fine, there is a little air gap so the rotor can move freely without rubbing. I don't understand why the driver side rotor is rubbing against the caliper? I checked everything over, the pads and rotor are the correct ones. I also took the pass side caliper bracket and installed it on the driver side and same thing, the rotor still rubs against the bracket.
View 13 RepliesFront caliper replacements--fwd? Person I bought this from said they'd just relined the brakes before I got it. After having it a week, I randomly checked torgue on lug nuts...a whopping 80 ft lbs. So now I have the vibrating rotors. When I back up I hear scraping like a bad set of bicycle brakes against an out of round rim. The pads are pretty thick. I bought new rotors and pads but I wonder if I shouldn't get calipers as well. This X likes to bite me in the butt--something simple is always about 5 times more complicated than anticipated.
View 1 RepliesI need to replace the rotors and calipers on my 04 accent gl. I noticed there are 5 bolts on the back of the caliper. I know one is for the flex hose connection. Then there are 2 big hex bolts closest to the dust plate. Are those for the caliper mounting bracket? and if so will they need to be removed? Then the final two are on the outer edge, however the top one is rounded and rusted, is this normal? The one on the bottom is a hex. So what needs to be removed to change the rotors and pads? I also notice that there are two screw holes in the rotor, that I guess snug it in place against the hub, however the screws are missing. Is this bad? are they needed? and if so can I get new ones?

Then caliper mounting bracket wouldn't fit back between mounting bracket and rotor. Loosened the hub nuts on rotor, and fit mounting bracket in place. Then torqued down the hub nuts again, and rotor rubs on mounting bracket and rotor/hub won't turn.

I never got a clear answer from him on what his mechanic said about it. Five to Ten fill ups later the Check Engine light went out on its own. Engine seems fine. Could this have caused damage to the engine or emissions controls? Would a computer diagnostic from a mechanic pinpoint any problems? Would you recommend a computer diagnostic be performed?
View 6 RepliesMy brakes sometimes feel like the rotors are warped. The problem is that it isn't consistent. I remember how the original rotors warped and they were crap so I put some drilled and slotted rotors on about 150,000 miles ago. Currently but not all of the time it acts like the current rotors are warped, the steering wheel will move back and forth, feel the shake in the vehicle. But today running a few errands at lunch, there was no wobble etc. I might go ahead and replace the rotors/pads but want to be sure that is the issue. Could it be the hydroboost on the 7.3? ABS?
View 6 RepliesRecently bought a 2001 Excursion 4x4 but failed to take it on the highway and get it up to speed. It shakes real bad around 65 but I can't tell exactly where the shake comes from. Here is what I've fixed so far. Balanced tires, Alignment, Fixed Steering Linkage, Balanced rear drive shaft, new shocks, new brake pads (slightly warped rotors but shakes w/o braking), lubed everything, replaced all fluids except transmission which was clean, no metal in any fluids, removed front driveshaft. Checked wheel bearing as best as I can.
View 5 RepliesI pulled a brake caliper off for inspection, and when I reinstalled it, I managed to strip one of the holes on the caliper bracket when putting one of the 7mm bolts back in - haste makes waste, ya? So, I am trying to find out my options, is it possible to get it re-threaded, helicoiled, or is it toast and I need to buy a new one?
View 2 RepliesI'm going to replace the rotors & pads on the X, was doing some research and read where slotted and drilled rotors actually create weak points in the rotor for vehicles this heavy.
View 14 RepliesI'm having a hard time trying to remove one of my rear brake rotors.
I thought these simply pull straight out and off, but mine might be rusted in place. I soaked the front facing area around the axle with Kroil and then tried jolting it out by tapping it with a rubber mallet. No success
What's the trick?
I read a reference to the front brake caliper bracket bolts being one time use torque to yield and must be replaced every time they are loosened. Is this true?

My front disks are pulsing & the thickness is near minimum, so I guess I'll have to replace them soon. Is any particular brand better than others?
These stock ones are made by Bosch and I'm not impressed with their lack of resistance to warpage. I see "Drilled and Slotted" available at Rockauto. What's your experience? Are they any good?
I have a 2014 Supercab Ecoboost F150, which has 37k KM on it (23k miles). I work at sea for 4 weeks on / 4 weeks off so the truck sits a fair bit. I had it in the dealer for scheduled servicing and they noticed the inside pads on both front brakes were wearing significantly more than the outside (4mm vs 7mm). The lube guy at the time had suggested sticking calipers and that they'd be warranty.
A few days later I brought the truck back in to have the brakes looked at and an unrelated warranty item done. They looked and said the calipers aren't sticking and the rotors are grooved and rusted, particularly the inside surface. They wanted to put new pads on and turn the rotors for 400 bucks.
I had a hard time believing it wasn't the calipers, and I was having a hard time getting a good explanation from the service writer of what was going on. So I took the truck back and pulled the pass side tire off in the driveway to take a good look.
As far as I can tell, the calipers are free. The slide pins are nicely lubed and are free, and the pads are free to move in the anti-rattle clips. I squeezed the piston back with a set of C clamps and it seemed to be good. Also, the pads are wearing more or less evenly (not tapered or anything), just the inside is worn significantly more than the outside.
So, rotors wearing out in 23k miles? They aren't really warped, just heavily grooved. My theory at this point is that the weeks the truck spends sitting allows too much corrosion to build up on the rotor, which is getting caught up and wearing down the pads and rotor. Maybe the outside of the rotor isn't nearly as bad because it gets hosed down and washed more frequently?

I still have 7 months of bumper to bumper warranty. Ford says the only cover brakes if the damage is caused by a caliper, so I think I'm out of luck on that front.

i have the brake (!) the ABS and the VSC lit up after i got new bearings and new brake pads and rotors, the car was also stalling before the mechanic removed these bearing "dust cover" circles that must have been causing speed sensor interfernce bc the spedometer was stuck on 0....so the car seems to be done stalling after those were removed and all the big lights went off then i hit the brakes a few miles later and those three lights came on...
View 2 RepliesI noticed the front brake pads were touching the rotors when I was painting the brake calipers. I had my e-brake engaged and in park. I'm assuming the e-brake only brakes the rear wheels because the front rotors were still movable. Although the car still rides fine but I'm not sure if this is normal.
View 1 RepliesJust thought I'd ask, I was at the dealer last week and while there asked them to take a look at my brakes because they were making a slight screeching sound but only when first applied when speed was slow.
They said it all looked good but that the sound I was hearing was from grooves that had been etched into the driver's side front rotor. I find it hard to believe that my rotor would have grooves in it after only 21k miles, considering I don't track it or drive it aggressively that would have caused that.
How to remove the front brakes pads and rotors on my GMC Sierra 2008 - 1500 - crew cab - 4X4.
View 2 RepliesI have never experienced what others have described as the brake delay issue, neither before nor after the ABS recall. I have even purposely driven over rough patches of road to try to duplicate.
After two days of rain, I noticed yesterday that my brake rotors were rusty. I remembered a comment from qbee42 about putting the car in neutral while braking in order to remove regenerative braking and to force friction braking to clean rusty rotors.
Yesterday I was approaching a stop light with plenty of distance and no one in front. I started braking around 45 mph with regenerative braking and then pulled the shift lever to neutral. When in neutral and with the regenerative braking removed, I felt the decrease in braking when transitioning to friction braking and I had to brake a little harder in order to have the same amount of braking as before in regenerative braking.
I can see where someone can "perceive" this as a surge forward but I only interpreted this as a decrease in braking force, as others have stated here many times.
I tried this again at the next stop light and felt the same "sensation" again and had to brake slightly harder when in neutral in order to have the same braking force. It was apparent to me that for the same brake pedal position that the friction brakes do not exert as much braking force as the same pedal position with regenerative braking.
Is this similar to what others are reporting as "brake delay" or "surge forward" issues?
I had my front brakes replacement a couple of months ago but I noticed that when after making a complete stop & letting the wheels roll, I hear a squeaking sound coming from the brakes. I had this checked by the local shop & was told that the piston is not disengaging with the rotors. Is this accurate or do we just need to lubricate? Also, if the pistons are defective, will this be covered under warranty?
