hey guys!

im not sure if anyone else has had this problem, so i figured id ask yall since you guys know more about these bikes then i do haha

anyways im having problems with the fitment of the front calipers on a 88 cbr.

all parts were purchased from sellers on ebay.

forks from an 87 cbr600

wheel & rotors from an 88 cbr600

front calipers & brackets from a 88 cbr600

for some reason the left hand caliper bracket wont fit on the rotor...pics below





also on the right hand side, the bottom slide pin seems to be too long..





does anyone have any ideas what is wrong or missing?

any help would be greatly appreciated!!!

thanks

come on guys!! lol

 

I'm pretty sure you have to completely install the caliper to the bracket before mounting it onto the bike, and then drop the whole assembly over the rotor & onto the fork. Otherwise you can't get the caliper to slide onto both pins with the rotor in the way.

There shouldn't be any fitment issues since everything is compatible between the 87-88.

 

Not many 600F experts online right now. Be patient...

If I were to guess, and I'm no F expert, I would say look at either your wheel spacers are on the wrong side making the wheel off center or the parts you got are not compatible or misrepresented years.


Edit: There's one now. Thanks Tahoe!

 

You do install them as an assembly, install caliper to bracket and than to bike.

 

Wheel spacers could be an issue too if they aren't installed right as Demon suggested..

edit: here is a pic of the exploded front wheel diagram..

Thanks for the info guys, I'll check the spacers nd see if that's where my problem is.

Also I forgot to mention that this front end is being used on a 83 gs1100 with the GS triples....I didn't think to check if the CBR triples were the same width apart as the gs triples.....lol

 

Any chance that the rotor is bent?

Listen to these other guys. Bolt that caliper on then try. These are floating brakes and they should have quit a bit of wiggle room, but only if both sliding pins are in. If they don't move then you should probably go over everything with polish and brake clean then grease it all up.

 

the rotors arent bent, i'll try assembling the calipers on the brackets first before installing on the forks tho.

the slide pins could use some new grease, they are pretty dry.

 

This could also be the problem. I would definitely check the fork spacing on the CBR vs GS triple clamps and see if they are the same.
