Is everything tight back there? the rod from the frame to the brake plate? How are the brake shoes? Is the cam going over center?

hard to tell at the moment,it was working fine and them bam,just started acting up.im gonna pull it down saturday and take a peek and see if there is anything obviously wrong.thought i would ask for ideas first.

Sounds like you snapped one of the springs that hold the brake shoes together.

I opened a topic about it a while back

That's the normal behaviour of the CB750. Just learn to live with it.

I just replaced my shoes on my 500 and the my local Honda Stealer didn`t have the springs so I went to Advanced Auto Parts and they let me go through their car brake kits,I found a perfect match for my old springs and all is good.

raul,i know what you mean by its a somewhat normal thing for these bikes,but this issue is not normal.im still leaning toward the broken spring thing.

The easy lockup on a 750 is normal, but the loud clunk isn't. The springs are part #95014-74320 and still available from Honda for around $2.15 each.

thanks jonesy,ill call em when they open

No prob!

(You did pull the brake shoe plate off and check out everything in there, right...?

)

dusterdude · « **Reply #12 on:** June 10, 2005, 07:16:50 AM »

jonesy,not yet,thats tomorrow,im in assuming mode right now.btw,for everyones info the brake springs are no longer avaiable form honda,however ebc supposedly puts them in their brake shoe kit.the part number is 320,i ordered a set off ebay since i need new shoes anyway.so i guess ill see how it goes.

Jonesy · « **Reply #13 on:** June 10, 2005, 08:14:05 AM »

That's odd... Service Honda can still get them.

dusterdude · « **Reply #14 on:** June 10, 2005, 08:49:22 AM »

well sheeite,how do i contact them?

Jonesy · « **Reply #15 on:** June 10, 2005, 08:55:21 AM »

www.servicehonda.com

They have an $8.00 minimum shipping charge, so if you are just going for the springs it might not be worth the money. If you already have a brake shoe kit with the springs coming, that's probably your best bet.

Come to think of it, I think I ordered some stuff from them awhile back and they wrote me saying a few of the items were no longer available, although the website said they were. Oh well..

Bet you real money service honda cant! They list everything then when you order it comes back deleted i havent had much luck with them , no parts bad comunication etc. Did refund the payment but didnt bother to tell me

Einyodeler · « **Reply #17 on:** June 10, 2005, 09:20:21 AM »

I`ve had that happen with Servicehonda too.They state it`s in stock then you play the waiting game and zilch.

dusterdude · « **Reply #18 on:** June 10, 2005, 10:18:08 AM »

oh well,i think ill stay with what ive got,thanks for the info.

dusterdude · « **Reply #19 on:** June 13, 2005, 08:22:07 AM »
