BETTER Brakes for $214
 
One of the things I haven't enjoyed about my 87 is how week the front brake is. Honestly I think the bike borderline dangerous to ride with the stock brake.
It gives "panic braking" a whole new meaning. :laugh And I have new SS lines and new pads with a good blead.

But I'm coming from a sport bike backgound where two finger braking is a norm.

SOOOO I did a little research and found this.

I checked again and the manual does call for DOT 5 brake fluid which surprised me.

A trip to Autozone for the last bottle they had of this.

Another trip to Lowes for a 1 inch and an 1 1/2 in bolt and some washers and this was all the tools it took to do the job. Well these two wrenches and a Mity Vac. If you don't have one I recommend it :)

It only took a few minutes work and I had this done.

Unfortunately the weather was a lot colder today and it will be tomorrow before I can test. But I have faith that it will be a great improvement. I asked the Wilwood engineer and he stated flat out it will work fine with the stock master cylinder. This a 4 piston caliper and it will have to have more clamping force that a single cylinder sliding pin design.

Tomorrow's ride will let me know how much better.

If anyone else is interested

Good write-up! Let us know how it stops.

upgrade to a floating rotor

Hard to tell from your pics but those look like un-graded bolts,definately not good for anything critical on the bike. You need grade 5 or 8 bolts.

Tom your chart doesn't include stainless steel bolts.

That's what I try to use almost anytime I install new fasteners. Do you have the numbers handy for that kind of bolt?

Alex, I'm almost positive the bolt grading standard applies to stainless bolts also.
Any good hardware store like Ace or True Value will have a wide selection of bolts in all grades and thread pitches. McMaster-Carr has a great web site for hardware. https://www.mcmaster.com

*EDIT*. I just looked and stainless bolts do have different head markings, so if you have high strength stainless bolts you're good to go!

Tom Your question made me curious so I did more research and found out it is difficult to get exact info on how strong a stainless bolt really is.

BUT I found this info on
Bolt Depot website

It is a common misconception that stainless steel is stronger than regular steel. In fact, due to their low carbon content, many stainless steel alloys cannot be hardened through heat treatment. Therefore, when compared to regular steel, the stainless alloys used in bolts are slightly stronger than an un-hardened (grade 2) steel but significantly weaker than hardened steel fasteners. Unless great care is taken, stainless fasteners are susceptible to seizing up during installation, a phenomenon known as galling.

So Sir you are correct!!! I need to replace those with Grade 8

You can also use socket head screws (the kind that come with that black finish) since they are at least as strong as Grade 8, usually stronger. Fortunately they come in chrome since the black oxide is neither attractive nor waterproof.

Edit: Grade 8 is minimum 130,000 psi yield 150,000 psi tensile, alloy socket head cap screws are minimum 162,000 psi yield 180,000 psi tensile. If anyone was interested in actual numbers.

Grade 8 replacement done before I even test rode it. THANKS GUYS :-)

The metric numbers divide by 6.9 willl give you strengh in psi x 1000
