Just replaced rotors and pads on the front of my 03 SuperDuty. Now my brakes squeal more than when the old ones were going bad!!! Squeals the most when you lightly touch the brakes. When you apply hard to stop the squealing stops. When I removed the old pair they seemed to be attached to the caliper with some sort of adhesive. could this be a cause to the new squeal since the new pads aren't attached in any way? It's driving me crazy!!!

 

Yes, that can definitely cause the squealing. Most pad sets come with the adhesive. If yours didn't you should be able to get it at most any parts store. The bummer is pulling it all back apart to glue them.

 

Did you remove the spacer from the back of the old pads and put them on the new one's? That is an anti squeal device.

 

What type of pads did you replace the old ones with?. Also put some anti squeel on the back of the pads...will help you problem

 

BTW...brakes are brakes..."Glueing Them" has absoulutly nothing to do with sqeel.....pads that are really hard and are metallic super pads will do what you are describing...I mean the pads that are gauranteed forever....nothing without a catch...excuse the spellin...few beers in me

 

Actually, that's not true. Pads should never be installed "dry". They need high temp graphite grease or anti-squeal put on the back of them. The pads will move in the caliper bracket and thus squeek or squeal. The grease is usually supplied with the pads should be added to the backs of them and allowed to dry til tacky then installed. Just my .02, the shop I used to work in did alot of brakes and we had to sit through hours of classes on this.

 

My point was that a spacer is not a anti sqeal device. You should always goo up the back of the pads and lube the slides with some lithium grease as well. Some pads that are lifetime pads are so hard that they will sometimes cause unwanted noises and they also do a good job of chewing up rotors.

 

Well, that ain't what you said.....

 

Hi SMc

Did you also put the retaining clips back onto the two new pads?

I had similar behavior when I changed my front pads a couple months ago. The new pads were so thick they made brushed the rotor lightly even while open. The light squeal would go away once firm pressure was applied to the brakes. Basically, I just waited a few weeks until they started to wear, and the squeal gradually lessened and finally stopped.

 

I've still got the original brakes on my '01 F250. With 59,000 miles on it, the left front brake emits a loud humming noise when applied that stops as I increase pressure. Is this the same as the squeal? The shop told me that there is nothing to worry about, as they are about ready to be replaced & they are simply vibrating. Any thoughts?

 

You are wrong on both post
1 the shims stop chatter and squeal by not letting the pad directly contack the rotor, it also alows expansion and contraction.
2 I have life time dust free brakes and they work great with no noise. Whenyou move out of 1950 and realise that technology have moved into the 21st century you will realise you might need to do some research.

 

I put the spacer pins back in, but it seems even after I release the brakes they still continue to squeal until I get up to full speed again. Makes em think that the pads are hanging up on the rotors. Yesterday I took them back off and applied the antisqueal to the back of the pads and it did help some -- still squeal occasionally, but no where near what it was like. It was so much and so loud it was almost embarrassing to have to stop ! I put Bendix pads and rotors on

 

Check your fluid level in the master cylinder, If it up to the top where the cab goes on you have too much in there. It will cause the brakes to drag slightly causing sqeaks.
