Rear brake lockup

hey guys I put in new brake shoes but took everything apart and cleaned it up put the rear brake pedal back on .the big coil spring behind the foot pedal fell out ,put it back where I thought it belonged .when I turn the adjustment screw the littlest bit the rear wheel is locked up and the peal has is still loose ,what could be the problem ?

 

the brake lever on the drum is way far back of where it is supposed to be for starterscloser to the 6:00 position
remove it and move it a few splines


notice location of bolt head compared to your location

 

Consider that the "split" on the lever should be generally aligned with the indicator slot on the cover. And BTW, where's your indicator arrow? Here's a pic of my drum (before and after some feverish rubbing, polishing and buffing!) You can see the arrow better when it was rusty in the "before" picture.

 

with out the indicator arrow aline the split in lever closer to indicator marks on drum

 

All valuable information thanks guys I'll give your suggestions a try and report back

 

Yes....take that lever off and rotate back counter clockwise to where the split is about at the 12:00 position

 

Good work boys ,got it sorted out .my next issue is I can turn the adjustment screw all the way in ,but the breake pedal dose not build any restance and the wheel just spins ,

 

Check the alignment of your brake pedal on the shaft. There should be a dot on the shaft that aligns with a notch in the brake pedal.


Then check the brake pedal travel adjustment.

 

The dot... and the notch... what a pair of bastards!

 

X2 what @Dadoseven said. Looking at your second pic, it doesn't look like the front is assembled properly and would just move the brake rod up and down instead of pulling it forward.

 

Exactly that's my issue what are your recommendations to fix this

 

Is this my pedal adjuster, not sure how it works ,Haynes is vague the little spring keeps popping off I'm also not sure about the large coil spring ,on the rear brake shaft ,just seems to flop around.

 

Your bike is different then mine I have a 81 xj650 maximum I can't seem to line up the dots without interference from the footrest, should I take it off to line up the dots

 

Take the brake pedal off, disconnect the rod end from the brake, push the rod forward and turn the splined brake pedal shaft to where you can get the pedal on proper.
Push gently on the rod... first photo it looks like it may be bent?

 

pull pedal off and aline dot and notch

once you do that you adjust the pedal hight with the adjuster

 

Yes, you are correct. Mine is probably slightly different. Do like @Stumplifter directs; take the brake pedal off of the splined shaft. Rotate the splined shaft so that the brake rod linkage is more up and down ( mine points to about 11:30, nearly straight up and down). The linkage will be close to 90 degrees with the rod. Reattach the brake pedal onto the shaft so that is in the proper position. There should be alignment marks on both pieces.

In your photo, it appears that the brake rod linkage is more at 9:00; so there is very little front to back travel of the brake rod. Maybe this is why it appears bent?

 

please put that in your signiture line or include it in your posts.

 

You are correct sir it is bent I lowered my jack by mistake and bent it

 

Thanks I will do that promptly

 

I'm impressed by your computer skills I'll certainly try your methods

 

Thank you for your advice I appreciate it very much

 

Sounds logical

 

We are all here to help you. Let us know when you get your rear brake working properly or if you have more questions.

Also, as a side note; you can multi-quote, putting more than one quote in a single post; In case you didn't already know that.? Select the +Quote of multiple posts you want and then select the "Insert Quotes" button.... or you can do a different post for each quote. No matter, whichever way you like.

 

Granny was right you do learn something new everyday thanks for the tip I'm not very tech savvy

 

But you do listen to Slayer... That's a good thing with Matti.

Some have called me Satan's Son,
A name I cannot deny.

 

IIRC the pinch bolt for the pedal needs to be removed completely.

 

1.I marked in blue where my dots are at the moment
2.I'm wondering about the little spring and which way it goes into the hole
3. Is this thing facing the right way or is it upside down
4.what is the purpose of the large spring and is it on correctly

 

the little spring is your brake light switch spring . does it have a string or wire on it ? it should be 1 piece.
blue dotts way out of alingment
large spring keeps pedal up when riding
your rod is on correctly
this link shows parts.
http://www.partzilla.com/parts/sear...1981/XJ650+-+XJ650H/STAND+FOOTREST/parts.html

start by disconnecting the brake rod at drum
then aline the dots. back the pedel adjuster out first
when alined adjust the pedle up some to hold i up about 1 inch below foot pedel
make sure the large spring is hooked onto what ever it hooks to you will need some help from a 650 owner on that here
when your pedel is correct hook up the rod. you may still have to move the rear lever to be able to thread rod through it

I have to go now but maybe the large spring hooks up same as a 550 I will look when I get home from work and post tomorrow if no one here can help you with the large spring.

 

1. Pretty confident if you line them up, it will fix your problem.
2. Not positive; I think it is the spring for your brake light switch. Perhaps someone else knows the proper insertion arrangement. I don't see an obvious problem.
3. Not sure about the way it's supposed to face on your particular bike, but I believe this is the correct orientation. Looks like it is the brake pedal height/ position adjustment. Mine is different. The stop bolt is on the pedal itself and hits against the foot peg. The nut though, should be snug down against where it is threaded through to lock it in place after the position is where you want it after you get the brake pedal aligned on the shaft correctly.
   1. Adjust the screw so that The pedal height should be 1.6 in (40 mm) below the footrest. Screw down the locking nut. Then you have to adjust foot pedal free-play.
   2. Adjust pedal free-play with nut at the rear of the brake link rod to give 0.8-1.2 in (30-40 mm) travel of the brake pedal.
4. This is the brake pedal return spring, so that after you press on the brake, the pedal goes back to the original position. Check it by pressing down on brake pedal. Does it spring back into starting position?

 

I appreciate your help

 

I lined up the marks just to see and the peal is way up in the air which explains the clearance issue with the footrest how am I to adjust the shaft to be able to fit the brake pedal under the foot rest

 

Remove the brake pedal, rotate the shaft clockwise so that when you put the pedal back on with the marks lined up it is in the proper position. From the picture, the marks will then be approximately at the 4 o'clock position.

 

How do I rotate the shaft I tried with my hands and it didn't budge plus I don't want to grip it with anything do I need to take the whole assembly out to rotate it

 

Does it rotate when you push on the brake pedal at all?

 

can you take a photo from the left side of the bike of the assembly

if you look at the assembly drawing you will see dashed lines rep the frame you can see where the adjuster bolt goes through the frame
the brake pedal shaft has to be under where the bolt passes through the frame.
from your photo it looks like it is above the frame
red arrow

 

I don't think you have that front crank (or whatever its called) in correctly. Here are some pics showing the correct orientation. What sucks is you have to remove (or maybe swing out of the way) the swingarm to pull this crank out and put it back in the proper way. I had a similar issue when I first put my bike back together.

These are off my 82 Maxim 650:

From the side, you can see where the rod hooks through the footrest bracket.



Here's one from underneath. The bracket must rest against the adjustment screw as shown, this also shows the spring orientation.

 

Looking at your pic, the adjustment tab is above the screw bracket. You need to pull that crank out and reinstall as shown in my previous post.

 

@jayrodoh those are the photos he needs .
if he backs out the adjuster bolt THEN supports the bike and removes shocks and tire it looks like the swingarm can be pushed up enough to remove brake pedal shaft

 

No but if I pull on the adjustment rod it moves back and forth

ya I did that thinking it would give me more room to get in to put the spring in the hole

 

Just some more food for thought...when I was overhauling the rear brakes on my 82 xj650 maxim I had to raise/lower the swing arm with shocks removed (can't remember which way I had to go) so I could remove, clean, and lube the brake pedal shaft as it was sticking to the point the spring wouldn't return it. Afterwards everything was extremely smooth and well worth the curse words getting it apart and back together in the proper order.
