'74 CB 360 Cafe Build - Luna - "Done"!

Re: '74 CB 360 Cafe Build - Boomerang

You didn't set tappets on overlap?
You will need to hold crank in correct position as the valve springs (plus magnets in generator) try to turn it out of position. I normally use a 14mm combination wrench on crank jammed against footrest or gearchange shaft (when you have rearsets fitted)
Basically, if you didn't have any trouble setting valves, you did it wrong ;D

It's the magnets! I hated setting the valves because of that! I even took out the spark plugs thinking it was compression but it still did it.

HA! I had trouble, but most likely not enough
 
Re: '74 CB 360 Cafe Build - Boomerang

Anybody want to buy a Honda?

Seriously, every time I turn around something else goes wrong.

Got a new caliper piston for the brakes, thought I'd be able to pop off the caliper, clean the bore for the seal and swap the piston lickety split. Seems that the brake pad is seized in the bore, along with the round pin. Tried drilling through the pad to pry it out, to no avail. I replaced the pad when I had the caliper apart originally and it went In smoothly IIRC.

Got around to reading some reviews on the aftermarket brake pads I picked up. Two things I've gained:

1) people have had problems with the puck being too large for the bore
2) they don't come with the nylon spacer/washer that sits between Piston and pad.

When I disassembled the caliper originally, there was no nylon washer present, so I didn't think twice about not having one. Some people say it's necessary, others don't. If Honda designed it that way, it's for a reason.

I do recall the pad being a bit tough going into the bore. I'm thinking I could've been running into the same problem where the pad itself is slightly oversized, but, not realizing that it's a common problem, I did nothing to repair. This would be causing the pad to bind and not return when the brake lever is released...

Now to get that damn pad out and replace. Think I'll heat the crap out of it and see if I can't get the round pin out.

Meanwhile to order a better set of pads. Any recommendations
 
Re: '74 CB 360 Cafe Build - Boomerang

My local Honda shop.

Looks like the outboard pad is there. But the inboard may not be available. The parts description says (see kit p/n end of block) I have no idea what that means. But, you could call them and ask. Maybe a replacement that comes w everything you need.

Re: '74 CB 360 Cafe Build - Boomerang

I noticed that parts diagram doesn't show the nylon ring. What's the diagnosis on that thing anyways. Mystery part?
 
Re: '74 CB 360 Cafe Build - Boomerang

Some of the brake pads come with it (Vesrah, Honda OEM, some don't. The older Honda OEM cames with them as part of the pad package....I think is allows the pad to move a little more and give better contact and acts as an anti-squeal.

Honda is weird though, they sell pads individually....

Re: '74 CB 360 Cafe Build - Boomerang

Just got off the phone with the Honda dealer, apparently Honda doesn't stock the OEM pads anymore so they sell aftermarket pads from EBC.

Seems like a strange part to discontinue.
 
Re: '74 CB 360 Cafe Build - Boomerang

Same with cj360 front drum brake shoes. They also disco my brake cable. Dcc has one that may fit. Oh well, at least someone else is doing it.
 
Re: '74 CB 360 Cafe Build - Boomerang

In my typical fashion, I'm jumping all over the place. Got to work making a plate mount, ordered some 90* LEDs and threw something together.

Threw on some new shocks from Progressive. Whoever made their fitment chart is dense, there's literally 1/8" clearance between the bottom clevis and the chain. The shocks are so far toward the sprocket there shouldn't be any lateral movement and minimal vertical movement
 
Re: '74 CB 360 Cafe Build - Boomerang

Brought the caliper over to pops' shop and we got to work.

Removed seized pad AND piston. Ended up drilling and tapping the pad (lol) and pulling it with a bolt. Then to find out the piston was seized as well. Soaked it in liquid wrench, compressed it with a c-clamp and then was able to push it out with compressed air.

Turns out the piston I put back in, SHOULD NOT have been reused. It was pitted, but I "cleaned it up" - or so I thought - before reinstalling. The piston ended up rusting itself back into the bore and seizing. What a mess.

What's the trick for getting the pin out of the caliper?

Waiting on a new set of pads, tomorrow will be re-cleaning and honing caliper, reinstalling piston etc.

Then I should have some working brakes
 
Re: '74 CB 360 Cafe Build - Boomerang

my Honda shop wants $91.65 for a new piston. :o I wonder what a machine shop would charge to turn out a new S/S piston.

Or this...$41.00

Here's the one I picked up, $30 and free shipping

Re: '74 CB 360 Cafe Build - Boomerang

There is absolutely no reason to remove the roll pin in caliper.
It's fun to block all the holes and heat caliper until piston 'explodes' out but it's much safer to use a grease fitting and 'pump' it out slowly. Any lever action grease gun can apply 5~8,000+psi. Never failed to get a piston out after I made a grease fitting for caliper ;D
Good deal on piston, I want to find out which GM phenolic brake piston fits, (needs shortening apparently?)
Phenolic doesn't transfer heat to brake fluid so should work better than stainless

+1 on the grease gun method. Safer way of doing it. Compressed air is less pressure but can launch the piston.

Phenolic would also be lighter.....Share the info when you find it....great way to reduce unsprung weight. I have an SS piston right now....It's a solid chunk of metal....kinda heavy.
 
Re: '74 CB 360 Cafe Build - Boomerang

Agreed. Couldn't find a grease fitting lying around to fit though :/

The thing did come out like a rocket though. Glad the dogs or anyone's family jewels weren't in the way.
