Time for brakes!

Well, if you've read my other posts, you know I'm neck deep in mods/resto mode.

I had a set of gold monoblock calipers set aside for the FJ, but last year the blue's seized up on my Venture/Max and rather than bother ripping them down in the middle of the season, I just dropped the gold's I had on the shelf on the Venture/Max.

Cruising ebay for a while now, I ran across a set of golds that seemed in decent shape and at least weren't "stupid priced", so I grabbed them:



Should clean up nicely. Paid 140 Cad out the door. That might seem a touch high, but I had to pay taxes on it since it was a Canadian seller (shop). I wasn't going to get out of it any cheaper bringing anything in from the 'States either, after shipping, duties, taxes and exchange rates.

Then, my "OCD" started nagging at me. "monoblocks on the front and stocker on the rear? It's gonna look stoooopid......pick, pick, pick.......nag, nag, nag....."

Arrgghhh! OK then, R1 rear caliper it is:



That did come out of the 'states, but only tipped the scales to 50 bucks CAD. 20 bucks USD, plus exchange and shipping.

OK, so it's not gold and it's not going to just bolt on. The gold part is easily handled and between the lathe, mill and spool gun, the bracket is something I can fix to mount to the FJ in it's "underslung" orientation. I woudl have bought an FZ1 caliper, but they're all fairly overpriced from what I could find. I've got lots of swingarm/rear wheel fabrication going on anyways, so this is just an easy addition. I'll either rework the R1 or FZ1 brackets I have, or I'll just make a sand mold of what I need and cast a new one and go from there.

I've got a 14mm Master cylinder out there on my parts shelves somewhere, purchased about a year and a half ago and never got around to installing it. It's a yammy with an adjustable lever, but can't remember what it came from. I can't swear to it, but I think it was an R6. Oldtimers setting in I guess...:)

Under slung back R-1 calipers get's the chicks


To get my front/back buttons to match, I sanded and polished the outside and used spray paint on the inside.
I was warned against removing the buttons, IIRC something about problems getting them to seal and hold pressure when the buttons were re-installed.

A tab was needed for the brake stay arm.

Cool.

You're a little more "polished" than I am, I'll be staying with the gold.

;)

I'll either weld the tab on or cast a new bracket, haven't decided which yet. If I go with a casting it won't happen until summer, I need to work outside with the aluminum smelt furnace. I could do it in the shop, I just prefer to do the stuff with lots of fire outside....

:shok:

As I understand it, you can remove the buttons. The problem is the proprietary seal behind them that, to my understanding, you can't buy. I also seem to recall something about the threading being a biotch to get apart without galling. I wouldn't doubt it's not a heat shrink fit as well.

I'm going to have a set of leftover blue's on the shelf that are pretty corroded. I might give them a try to see how difficult it is....for curiosity's sake if nothing else....

Hmm, I think you should stay away from riding upside down, the brakes work provide any stopping power with the wheel in the air  :biggrin:

Mind you, the black one looks sooo much better IMO - very tasty  :good2:

How does that rim work with no spokes Pat. :biggrin:

well crap.

R1 rear caliper came today.

Problem is, the R1 caliper bracket is too small for the FZR1000 disc. The FZ1 bracket is large enough for the FZR1000 disc;



but the lugs are too far apart to fit the R1 caliper:





Unlike a lot of guys, I like a powerful rear brake. I learned to use it when racing when I was a pup and it's something I've always used on the street. I use it for everything from settling the chassis, to tightening a line to reducing braking distance. I'm used to a powerful rear brake and that's what I need for my riding style.

So, I'm left with a few options here I guess. I could make a new bracket alltogether, but that's a butt load of work that I don't feel like doing right now.  I could try and modify the R1 bracket, but i'd have to cut it in half and add another section. Or i could lop off the rear caliper bolt "ear", weld it back on in the right spot for the R1 caliper and call it done.

Or I could wait for an FZ1 rear caliper to show up at a hf decent price, but that seems unlikley because, for some reason, most sellers seem to want a premium for them for some reason....

Should be easier to find than the FZ1 caliper

Actually, I'm not a machinist either. I've been a gearhead my whole life and it's taken that long to accumulate the tools I have.

Cars, trucks, bikes, boats, airplanes, helicopters, tractors, barstools, etc.

As long as it's got an engine, I'm in!
