Title: Rear brake actuator arm
Post by: ebmbiker on April 05, 2022, 09:09:30 PM
Good evening folks,

As my CB500K1 came in pieces, in boxes, I’ve got a couple of things missing. I’m missing the rear brake actuator arm and kickstart lever. Are these parts common across a few Hondas of the era?
If so, which ones? So I can start looking.

Cheers, JB

Try the CB-Four website in Germany, they have varioous bits that are second hand but in really good condition. Send them an email if you cant find what youre looking for, they're really helpful.

No Oddjob, it's part number  43411283000, the lever arm on the brake backing plate.

That's actually a CB450 Black Bomber part and carried on to the the 5-speed model ..so you can search for those models too to find one.

Not a criticism of Julie here but why do people have parts rechromed but never do something about the bad areas that Honda left rough. The edges and even some front parts of the lever are rough, you can see dressing marks from production etc and the rear is rougher than a Moss Side whore. The arm itself it lovely, good chrome job but it could have been so much better and for the same price, same thing applies to gear levers, brake pedals, 550 chain guards and even some parts of the 550 grab rail, it's a real shame.

I know the argument goes but you can't really see it so why bother? Well the same would apply to the 500 fork stanchions, they didn't chrome them where they were hidden by fork shrouds and look what happened there, rust so bad people where forced to change them before they knew about hard chroming etc. Plus it's where rust starts, because the surface is rough the chrome doesn't adhere properly and that lets water in and that's the end of that finish.

AGAIN, nothing critical of Julie here, just a bit of a moan about why this happens.

It's all a matter of taste Ken but I personally hate it when chromers polish out the original casting marks on Honda parts and make them resemble something that  came out of bathroom fitting shop. The guy in Hull did that to my CB750K0 rear brake arm and I voted with my feet after that. But, as I say, it's all a matter of taste. Allenchrome were good in that respect as they would either do show 'blingy' chrome or 'Japanese bike' finish where they did a less blingy finish and left the casting marks alone.... depending on what you asked for.

Sadly the b*ggers won't do stuff like that now...well they won't do small batch BZP so I doubt they will chrome old motorbike parts.

I never have casting marks, original poor finishes, rough finishes etc polished out when I have parts re chromed. I cannot stand chrome parts that look so unnaturally perfect that they actually look like plastic chrome. It reminds me of all the show bikes,  that were shown at custom bike shows in the 80's, cheap, tacky and nasty. As long as the bike goes well and is fit for purpose and the parts do their job, I'm a happy bunny 😊😊😊

I agree with Julie. Bling bling bikes came later, when they stopped fitting those useful harmonica boots over the front legs. I believe the F2 was the first with shaved, shiny legs and IIRC even a crome cover over the drive chain. Every now and then one sees these Honda's with parts polished to a degree they never ever had before, not even in the showrooms, nor in the ads. Personally I prefer the original 'satin' look.
Title: Re: Rear brake actuator arm

I remove all casting marks, unless they are interesting, like Japanese symbols I found on fork sliders recently. They are unsightly, allow dirt to grab a hold onto, allow corrosion a foothold. Plus to me they show a lack of attention to detail, of course we are all different. I dislike the patina look that some seem to like, to me that makes the bike look untidy and unloved, I much prefer mine to be good looking but rideable unlike show bikes, although I did win a few shows with the L reg 500 when I restored it the first time, which is odd as I never entered the shows in the first place, I got persuaded to enter by the organisers when all I wanted to do was look at the other bikes.

Don't know what you mean by shaved legs DR, yes the 550F2 was the first to lose the fork bellows but it looked miles better for it IMO, of course it also allowed the fork stanchions to be hit by stones etc but it also allowed a better view to spot leaking fork seals, it's more streamlined and modern. You can't really mean you prefer the old horrible 500 chainguard to the 550 chrome one, to me that made the bike look OLD even when it was new, they might as well have fitted a bottom guard so the chain was fully enclosed like a C50. Couldn't wait to bin that. Nothing wrong with a bit of bling, just not OTT.

I love my rubber harmonica boots. How many here can say they never had to replace a front leg seal? Mine after 46 years and over 138.000 still don't leak... and yes, the legs underneath look a bit rusty. Who cares?
It's a matter of taste ofcourse but a chrome cover over the no doubt dirtiest part of the bike, the drive chain. I find it ironic. Chrome is for H.D lovers. In the 70s and 80s no owners of CB Fours polished their bikes to a degree, you see now. Even in the ads they weren't.

You must have not gone to many shows back then, it was all the rage in the 80s as the bikes grew older and more tatty. I had loads of parts chromed in the 80s, including fork sliders and all the engine casings. Some Kwacks of that era started coming with chromed engine casings, seem to recall the Z1300 was one.

HD lover, how very dare you, can't stand the things. Better suited to ploughing fields IMO.

Clearly you never saw the 500 Benelli six that the drummer out of Slade owned, now that was OTT.

It was Dave Hill and a 750 Benelli six, still around as well.

I like his story that he needed a new house with a bit of privacy to get away from all of the screaming fans. He bought this nice quiet place only to find after he'd bought it that there was a girls school nearby.

For the record Dave Hill was not a drummer…..some say he wasn’t a guitarist either, but they would be very wrong. I thought Slade were a good band actually and knocked out some good tunes.

Knew that Phil. I thought it was the drummer but after looking it up on Google I noticed it was Dave Hill who was the guitarist. I saw that bike at the Belle Vue bike show around 75-76 IIRC, I seem to recall the colour scheme was different then but I've since read he had 3 sets of paintwork done for it and changed them around every year. It was the most metallic paint I'd ever seen, done by Dream Works, it was so metallic it looked like it would cut your hands if you stroked it.

Either Bryan, HD are the only bike to come with plough attachments on the swinging arm  ;D ;D

He's still touring as Slade, only one left so he claimed the name. Noddy was thinking of reforming the group for some performances. They are all still alive so it may happen.

Thanks for the offer Julie, but your item is far too nice for my project. I’ve found a rusty one that I’ll blast and powder coat.

On the subject of removing casting marks, I do. I filed all the casting marks off the R6 fork lowers and triple clamp before they were powder coated. I don’t like parts to look like a sucked boiled sweet, just tidied up. Which reminds me, I should start a post in the Project section

It's like a piece of Chippendale furniture, do you want it still full of dry rot and woodworm or do you want to see it in all it's glory.

Shame, if you wanted a rusty one I had one spare, I like to just muck about with spare parts so I started to tidy it up. Now has no rust, no chrome, no nickel plate, no rough edges, no hammer marks where others had tried to remove it and failed. I'll have it chromed and sell it on after I reckon. Or maybe I'll use it on mine. Not polished yet but still fairly shiny.

Here is a good example of what I mean by 'satin look' and it's that original look I prefer. The Yanks have a habit of exaggerating and making anything as shiny as a mirror. Every new generation HD comes with more chrome. Not for me. With the satin look the bike looks original and in balance. By going beyond, other parts of the bikel come out imperfect. It will look unbalanced and vulgar like too much make-up. It's a good thing the mirror like look will not last long. ;) All a matter of taste ofcourse

So you must hate the police bike James is doing as it's got quite a few unoriginal polished parts.

Spotted this the other night when i was trawling for parts on Ebay.

https://www.ebay.co.uk/itm/203913511655?_trkparms=amclksrc%3DITM%26aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D3d5f94b864b74efba6527cb0823cb551%26pid%3D100675%26rk%3D6%26rkt%3D15%26sd%3D294893858854%26itm%3D203913511655%26pmt%3D0%26noa%3D1%26pg%3D2380057%26brand%3DHonda&_trksid=p2380057.c100675.m4236&_trkparms=pageci%3A0211aade-bdc2-11ec-8cb4-ca5e170857b1%7Cparentrq%3A3404779a1800a44c1f288d16fffdeaa2%7Ciid%3A1

That's supposed to be NOS but I'll be honest here and say that's an awful finish on it, rough, casting and machining marks all over the place, chrome is pretty poor IMO. However they have plated both sides of the lever.

Saying that I finished the old lever I was mucking about with the other day.

I also found the lever which came off the bike I'm restoring, I must have got it plated by R&S in Manchester when I took some parts to be de-chromed. forgotten about it TBH.

Now compare both of these levers with the NOS one and honestly say you'd prefer that.

Old lever, sanded, polished but not chromed yet.

Newly chromed lever, TBH I don't think there is a lot of difference between the two except the chromed one is shinier.

Sorry Ken but I prefer the NOS one all day long. Honda chrome never looked like the  'blingy' chrome that most UK chromers do.
But it's all a matter of taste and very difficult to get chroming companies to replicate the original finish ... closest I ever got was Allenchrome but they won't do small jobs any more AFAIK. I feel exactly the same about mirror polished alloy on Honda's. On a custom bike or chopper possibly but on a restored to original Honda ..no.

Your right Ash, it is a matter of taste and you ain't got none  :) :)

I wouldn't mind if all Honda chrome was consistent, mudguards like that lever chrome and you'd have been complaining to hell and back, some is bright and how it should be and some is dull as dishwater and no one says hang on, that's a crap finish mate.

We had some Suzuki tanks coming out of the crates with sand under the paint, just because it comes like that doesn't make it right. To me it smacks of that's how it was and that's how it's got to be, again no offense but I can find loads of 750K0s and they all look the same, I'd much sooner one showed some individuality as all the same is boring. I think that's why stuff like Rickman and Phil Read reps are so popular, they don't look the same as the rest.

You think chroming companies won't do it because it's not bright chrome, I think they won't do it because it isn't really chrome at all, chrome is like lacquer, it's transparent, what you see is the undercoat, usually nickel., god knows what is under that lever arm. If they gave customers a finish like that back they'd go out of business quick I reckon.

Well just to please you I'm going to have the brake arm finished in another way, if I'm right it will be semi shiny. We'll see how it comes out.
