Hi Julie,
Thanks for that - never like to have parts "left over" when replacing things, always think I've missed something important...

Should have plastic shim  ;)


I have been trying for the past 28 years on and off to solve this problem and got nowhere.
We have every SOHC in our collection and 3/4 of them squeal just before you come to a stop. The worst one is the missus 400/4 and she also has a 550 that has never made a sound, strange when it is the same brake set up.
Over the years I have tried:
New brake lines (OEM rubber and braded )
New pads ( of all makes)
Skimmed disc's
New OEM disc
OEM piston
Stainless steel pistons
OEM seals
Aftermarket seals
Re bushed the pivot arm
New OEM master cylinders
Aftermarket master cylinders
Every type of copper slip and other brake grease

And on the 400/4 we got it quite after a disc skim but, after 2000 miles it was back again  >:(
Maybe if i changed the handle bars it would help  ::)

 3/4 of them squeal just before you come to a stop.

Do you mean in the final couple of metres or so?
Mine does a good squeal on the slowdown before stopping!

🤣🤣🤣🤣🤣 It probably is my fault Bryan, strange but true but I rarely use my brakes in anger. I just use the front brake, using only one finger on the lever, to come to a full stop. I use the back brake for slowing a bit when riding fast. I glaze the pads before they have even had chance to bed in. These days when the squeek gets really bad, Trig takes the pads out, scuffs them up and puts them back in and shes squeek free for a couple of weeks. I'm the same in the car, I have done almost 100,000 miles in my Freelander and I'm still on the original front pads and only the 2nd set of rear pads since I bought the car new.

That's because they spend 90%of there time broken down and when running they don't go fast enough to use the brakes  ;) ;D

OK heres one for you, i had to change the front pads on my Mitsubishi L 200 at 80,000,  plenty of material left but half of it fell off one pad. Now done 180,000 supose i should look at whats in there, although i did do discs and pads at 110,000 cos of a warped disc

I've got, or had (and will get back?) the dreaded squeak as well. After changing the pads then the disc it went away for a while, but returned. Because I had a fair amount of play on the pivot (pin was oval) I changed that, and so far no squeaks. Everything else in the front brake is new or refurbished. I find that cleaning the disc with brake and clutch cleaner on a rag is some temporary help. Back in the day, my first 400/4 never had this problem at all and I did a fair few miles on it. I guess that some material change has made the system more susceptible.

Not much help to you for 400 four fitment, but I fitted an EBC MD1062LS brake disc onto my CB750F1.

Cured the squeaking, improved the braking and now it also stops better in the wet.

Maybe the original Honda brake disc material is not so good?

I'll have you know young Paul my Freelander has never, ever broken down. I even managed to limp it to a garage when I filled it up with petrol, which was a bummer as shes a diesel 🤣🤣🤣🤣

I think he means the brake disc material Bryan. Not the pad material.
