Topic: Poor front brakes

Tru Disk here as well, excellent work.

Modern brake lines and second disc fixed the brakes for me on the K0

Ya they probably put it on a surface grinder. Can make it very flat that way.

Tom is very available by phone most any time. He told me he uses a Blanchard machine,whatever that is.

This is the one he did on my little Honda 200cc mini-bike CB125.
The bike has a mechanical,cable operated caliper,but now stops Very fast.

That's a rotary surface grinder. Does a beautiful job grinding things flat! Cheers, Bill

Godfreys Garage also does great work on our sohc disks and he is a member.  He drills and thins the disks to save unsprung weight.  https://godfferysgarage.com/

TrueDisk is the way to go. Excellent work with flat grind and drill for me and my K7. The front brake feels as good and progressive as the Brembo on my BMW. Reasonable cost and quick turn around as well

Here's one True Disk just did for me for one of my bikes;he uses a Blanchard grinder.

Is that the GS 450 rotor?

Yes 

[Deltarider]

If I prefer to keep it simple and just like to deglaze the rotor a bit, what grit sandpaper do I need?

He does excellent quality work.

 Hey colined, did any of this help?

I just used a palm orbital sander on my 550 disc, using 100 grit and it looks much better.

Is that a valid technique or do you risk a wavy disc surface? I was about to shell out to get mine resurfaced, if I can get it done in my garage I'll save myself the $175 + S&H

I don't see how it could hurt, but if I get brake vibrations later I will send it off to have it trued.
BTW, it was just a light scuffing to clean it up some.

Picture is right after (not wiped down with acetone yet).

I measured mine before and after and the thickness reduction is negligible. With a palm sander (or my rotating set up) we are just cleaning off the existing. But, it DOES  make for a noticeable improvement with a new set of pads. Looks good too!

If your disc is warped or severely corroded, this won’t fix it.

[Floshenbarnical]

Good to know. I'll be breaking out the 100 grit because they're in decent enough shape. Am definitely doing new pads though.

[seanbarney41]

You are highly unlikely to ever find an sohc4 rotor that is grooved too deeply or warped ...just too damn thick and hard...which is also a big part of why they don't really stop your bike very fast.  About the only way they ever get damaged is in a extremely severe collision.

  The best thing I have found after restoring my '76 750 was going back to stock Honda pucks I had since 1977.  Original pads from honda.  After restoration, I tried several puck manufactures and they all really were very poor at stopping power.  I then put on the "new" oem pucks I had saved for many years.  Instant increase in stopping power.  I do not ride my bikes enough to ever wear them out given I'm not a hard breaker and I coast a lot or let engine slow me down.  The new material in bike brake pads absolutely sucks.

Iron rotors are the best for stopping power.  Stainless Steel is pretty poor but it does not rust like iron.  The best set up I have found is old stock original Honda discs, clean rotors and TPFE lined stainless Steel hoses.  This is what I have now after restoring my 76' 750.  Front brake is crisp response, tight for the lever grab and does a good job of stopping the bike in an emergency situation.  Two fingers on the brake lever is all I need, three in a panic stop.  Very linear response with clean MC and caliper with SS lines.

Where do you gents buy your pads from?

[BenelliSEI]

If your local Honda dealer can order a set from HONDA, go there first.

[PeWe]

Find really old NOS pads with asbestos?
