Only bike I have ever had that the brakes squeal replaced rotor with a stainless one and put lyndall pads still squeals any suggestions bike is a 91 softail

 

Check wheel alignment and make sure caliper is centered on the rotor.

 

Did exactly the same to my 97 E Glide because of a worn rear rotor.
Never figured out exactly why but that combo made a ton of squealing with light brake application.

Ck'd wheel alignment, rotor and caliper. had 2 indy's look at it, no help.

Went to some plain ol EBC pads and it helped alot. The next time the rear wheel is off that stainless rotor is going away.
Didn't have the noise before.

It's not so much the rotor as is the pads. If you're using any pad that consists of ceramic or hi metallic compounds they will tend to squeal under light braking conditions. I use EBC organics with no problems at all. In fact the front grab so good that 2 weeks ago, I was cornering way to fast and had to hit the front brake very hard to avoid going off the road and hitting a huge Maple tree. If I relied on the rear more I would have spun out. I would probably be hurting still....

 

Will try ebc organic pads,have lyndall kevlar now

 

Honestly they do work very well and there's hardly any brake dust which is a huge plus.....

 

I had the same problem with my '93 that had sintered pads which were aggressively chewing at the rotor. Switched to organic and the squeal was gone.

 

Let me apologize to all that took my advice on brake pads. I need to correct my last post on the type of Brake Pads I am currently using. I DID NOT PURCHASE EBC ORGANIC PADS I thought I did but what I did purchase was Twin Power Kevlar pads from the MotorCycle superstore. Both front and rear sets only cost a total of $43.72 shipped. Sorry if I mis lead anyone. I don't know what I was thinking. I will say though that they work very, very well and there is no squeal what so ever..... Again I apologize.....
