Title: Rear Disc brake after market replacement
Post by: drifter-paul on May 21, 2014, 02:28:23 AM
Time to replace the rear disk (140K) on my '99 1500. Stock is about $240 and they were powerful enought to lock the tyre on occasion; but they are undrilled and do get a bit hot after sustained energetic use.

Just wondering if anyone has used a non OEM disk.

I read the "125 1500 Drifter parts" post, but he only has 6.54mm on his. The min is 6 and new would be 8. I 'm on less than 5.9.

My rear disk is drilled, and at 84,500, it's just fine. What kind of pads are you running that would tear it up so quickly?

I use EBC FA231 on the rear. Get about  30,000 out of them.

I think my rear is drilled also.  I'm also using the scintered pads but haven't noticed any significant wear on the disk (nowhere near your mileage though).  I use the rear brake a lot is it seems to have an unusual amount of braking influence unlike the rear brakes on most bikes.  I guess there's some benefit to a 700 lb bike.  :D

PS: I picked up a brand new, still in the fishwrap, OEM rear disk on Ebay for cheap a few years ago - thinking I might mount it on the front (so the front would have drilled holes too).  I've haven't got around to checking if it fits yet - it's sitting on my long term spares shelf.

Won't fit on the front..not even close. Mount holes, caliper and spacing are all different. Classic drilled disk should fit. Why not send yours to Australia?

Well, if it doesn't fit on the front, it'll have to do as my spare for the rear.

On a related note.....

I notice that the drawings of the 1500 in the beginning of the Factory Service manual shows a drilled front disk.

Have a new rear disk coming from the States, thanks for input.

Probably too late but I saw one on EBay for $35 (I think)

New Disk has arrived  :)

My Clymers Kawaski VN1500 Classis 96-98 lists Brake Disc bolts as 23Nm / 15 ft lbs . This seems modest. :-\ Can anyone verify this from another manual.

Also I have Loctite 263 (High strength/180C, heat to remove) and Loctite 243 (Medium strength/180C). Do I need the 263 ?

Is a hair dryer enough heat to loosen 263 ?

Thanks all

The Kaw book says all brake disc bolts should be 20 ftlbs (27nm).  Most folks use blue loctite (243). The books says use some but doesn't say what type.

As far as loosening high temp loctite... I've never tried a hair drier, but I really doubt that would ever get hot enough to loosen the loctite.  I think you would need a torch- at the least a small butane micro torch - it really depends on what you're trying to heat.  Whatever you're heating that is loctite'd more than likely conducts heat, so something like a hair dryer won't heat it fast enough to get hot enough.
