Title: rear caliper issues....
Post by: BlackKat on August 29, 2010, 04:15:43 AM
So on my way home from the Mods Vs Rockers show yesterday the rear caliper on my 99 750 locked up. I pulled over and after about 10 minutes she cooled and released. Knowing I need a new caliper in the VERY near future, is there a better caliper I can update to with little to modifying? I say little to no modifying because I have a set of Paul Smart wheels to go on over the winter.....

quite ironic as I updated the front brakes yesterday to a twin set up from a 900 and matching 748 clutch and front brake masters before I went up to the show...DAMN!

this is a repeating situation for the board. in the tech section I've read several threads.
most point to too little play in the brake lever.

interesting...that very well may be, however, I am going to buy a new caliper and have i rebuild by my local duc tech no matter what as I have found that the previous owner of my bike did very little in the world of taking care of the bike. I'm quite certain the brake fluid was never changed in 13k miles. It was very low, almost dry and full of...maybe rocks and sticks ;). For the most part, everything he touched has issues.

Just something for my peace of mind. Thats why I posted here rather than tech...looking for an alternative to provide better breaking and balance a little closer my new twin set up in the front.

Absolutely, but the possibility exists that caliper and master cylinder parts could have been overheated if the bike was operated long enough with the rear brakes applied.  Some have gone on fire!!

having rear one of the posts about this, I have to make a couple notes...I TOO am running an EX BOX...my rotor after being run a short distance at highway speeds was glowing orange! I do run ATE Super blue racing brake fluid as it has the highest boiling point of any fluid I can find on the market.

All these factors considered, I still want to buy a replacement caliper just to be on the safe side...

If the problem is the bleed back in the master you might just fry the new caliper too

I understand that and I'm not by any means ignoring the advice, I am just asking simply, once other existing factors are addressed, is there a better caliper that I can update to...anyone?

Define 'better'.  The stock Brembo goldlines are pretty decent and certainly more than adequate for what they're asked to do.  I'm sure you could find more expensive ones.

There's 'race' style Brembo rear calipers, but they're set up to be run low mount, like on SBK's and S*R.
They're extremely expensive.

ok, I am not against buying a used one. My 99 runs the rear as a low mount. What would the caliper have been stock on (or was it ever?) Model number? Something I need to look for?

I'm not saying I'm mr money bags, but I'm not afraid to spend money if its worth while. I would like better stopping power.

Define better?

As we know, the Monster isn't actually fast, so I have to "stay in it" longer and brake late when I ride with some of my buddies. As I said above, I just updated the single caliper front to a twin set up and I'm sure that is a HUGE difference, but if there is a better performing (that is, better stopping power, lighter weight, more reliable...what ever scale you choose to measure by) caliper offered on another bike that would mount to the low mount rear system on my 1999 750 Monster, I would love to know more about it. Knowing the circumstances with the current caliper on the bike, NOW would be the time to do the update.

PLEASE?

Not to be a downer...

rear brakes aren't all that effective in the first place.

I'd concentrate on making the front brakes as good as possible.

I can appreciate that, but understand...there is an issue with my stock set up...PARTS ARE GOING TO BE PURCHASED while I address all other factors mentioned.....


Is there a different caliper other than the stock caliper for my 1999 750 that I could buy that would offer ANY benefit?

This caliper is the one I was talking about.
Pay no attention to the mount at the bottom.

I'm sure it's a good caliper.

For that money, I'd get a stock style caliper, a set of Ferodo SinterGrip or Platinum pads, and a BrakeTech iron floating rear rotor.
Or someone else's rotor, no sure if the B/T is available.

all of this sounds like a great way to invest a lot of money in making it easy to lock up your real wheel.
i don't know about you, but through my rear brake lever, and my stiff sidi boots, i don't get a lot of pedal feel for that rear brake.
i use it on gravel, and in emergency stops. that be it.
