Title: new brake rotor
Post by: Matt Chapter on March 06, 2012, 01:17:57 PM
Check out what I recently received: (https://bmwr65.org/smf/proxy.php?request=http%3A%2F%2Fwww.flickr.com%2Fphotos%2F77662887%40N05%2F6959592057%2F&hash=613433d5f4f35f1b316c53a156a51f59ca176873)

My old rotor was uber warped.. visibly so from across the parking lot.  The guys at Spiegler had this back to me in about a week, including shipping time.

Once I got the new rotor, it was new shoes time.  Lone Star had a 90 / 90 Lazertec in stock, so I went with it.  After all that, I got new fork seals and fluid installed from On Road / Off Road Cycle.

The trickest part (other than stripping the fork pinch bolt  [smiley=smash.gif]) was finding and installing the new brake pads.

Apparently the '86 - '88 single rotor R65s take an FA77 ebc pad, not the FA18 or FA171.  It took three stops to Lone Star for them to figure it out, even after I brought in the old pads.

Then, I discovered the best and worst ways to push the brake cylinders back into the caliper.  Worst way first : attempt to push the pistons in, have no success, swear, unbolt the calipers and get the o ring caught when the brake fluid starts to leak out, covering the floor and making a lovely sucking sound from the master cylinder. More swearing. Once you have the caliper apart, the pistons push in easily, but messily.  The best way : (which I'll try next time) undo the bleed valve, push the piston in, viola!

No more shudder, lots of grip, nice firm front suspension.. I recommend it!

Spill it, Matt. Is that Spiegler's $39.95 R65 rotor or something else? ;)

Nice looking disc! I like!

Man, that's some ugly sh*t they tack to your bike in VA! Hope that doesn't catch on out here!!!

The easiest way, actually, of installing new pads is to - first clean off the pistons -  then wedge them back into the bores using a couple thin pieces of plastic to protect the pads and a hardwood wedge, or two large screwdrivers gently levering on them.

They'll go back in, but you do need to watch the reservoir because the fluid displaced will return to the master cylinder and can overflow.

Spiegler is the rolls royce in m/c brakes & rotors.  You get what you pay for - quality!

I believe it's $240US per rotor for the semi floating modification .

That's what I paid about 18 months ago for a set on my '82 LS

They must have had to ship it further to me than Bob... my bank account shows $252 for the rotor.  For me, the semi-floating adaptation is a bonus.. I just knew I didn't want to pay 480 seashells for a new 1980s tech rotor!  The process was a piece of cake, too.. you just ship your old rotor in and they clean up the carrier, install new shiny bits, and send it back.  Put a piece of paper with your name and number on it in the box so they know where it goes. ;)

Then 49$ for "BMW" brand brake pads, $282 for the fork seals, small shim, and another $180 for the new front tire (I brought the rim in off the bike, and the service guy had a hard time trying to figure out how to charge me so little for labor.)  Hopefully these improvements will last a while, because this hobby is getting expensive!

I'd already replaced the original brake line with SS lines, and replaced the master cylinder, so the brakes are in pretty good shape now.. pretty much the best feel of any motorcycle I've owned. (The R65 is the newest bike I've owned.)

Wirespokes - you're saying to use the old brake pads to push the pistons back in?  Did you unmount the caliper?  I couldn't get much leverage anyway I went at it.  I tried with several items including a clamp or two and couldn't get them to budge, thus me getting "inventive"  ::) and making a huge mess.  One advantage of doing it this way was the the old brake fluid, somewhat gunky, got ejected instead of pushing it back into the lines.

Also, sticker wise, you mean you don't have a local parking permit, state inspection, and locality tax sticker, plus registration on the license plate?  I'm lucky I had the sticker plate, even if it's pretty beat up now.  The state inspection sticker color changes every year, and they wanted to put the stickers on the forks!  I've since moved to Texas, where, as Monte was just saying, nobody cares.

Just in case you didn't know this, the Spiegler floating conversion, is rebuildable by the owner, no special tools are required, they have all the parts on their site .

Those robber barons at Austin's Lone Star BMW-Triumph are getting pretty pricey for their fork seals up there on North Lamar. Extra key stroke perhaps. Maybe $28. As a Lone Star customer myownself, I sure hope so!

The drill pattern in your new Spiegler disc will most likely eliminate the usual rippled n' groovy OEM disc rotor wear pattern so often seen on Airheads with some mileage on 'em.

Perhaps Bob Roller received a volume discount from Spiegler as he bought a brace of rotors for his LS.

With your all new, super stopper front end package, you'll be carding some powerful and impressive stops. That new tire doesn't stand a chance in Austin traffic. ::)

No, I ordered two rotors and a three hose set of stainless brake lines, the order was over $500, shipping is free for orders over $500 .

I guess I wasn't clear.. I had my guy at On Road Off Road do the fork job, so that number includes labor.  I guess I could have done that part myself, but you know what they say: when you want it done right, hire somebody who knows what the hell they're doing.  ;D

And so it looks like shipping from Spiegler to my house for a rotor costs 12$.  Not too bad.  Not like I could ride up there with no front brake for less.  And traffic-wise, when in doubt, go around.  Or get up early and beat the traffic.

I fear for this new tire no matter what.. I locked up the front tire backing out of my driveway on Monday.  Just enough to leave a couple inches of rubber, and a little chirp, but shesh!

I watched over the shoulder of your Austin-based On Road Off Road guy as he worked his magic during a track day last year at MotorSports Ranch.  http://www.motorsportranch.com/  He had bikes lined up and riders waiting to shove cash in his hand to get their scooter's suspension tuned.

Later on, while he was away from his untended trailer and pit service area, I was passing by and snagged some arse trying to steal a pair of pliers out of his trailer! Had the brass to tell me he was the business owner. He wasn't and I made sure the pliers were left in place. Jerks everywhere.
