Checking my Rear Drum Brake

Hello everybody,

I'm completely new to XJbikes.com. Last week I bought my Yamaha XJ 700 Maxim. I've read a lot on the forum and today I checked my rear drum brake. From what I can see, my rear drum brake should do fine (I compared it to this topic and pics: http://www.xjbikes.com/Forums/viewtopic/t=15874.html).

But to be sure I wanted to show a picture of the brake, just to make sure it won't come off when I'm enjoying a ride!

On the left and right side of the brake you can see some brown rust (?). Does anyone know what I can do about that? And could it be the start of some trouble?

Hope you guys can help me.

Ps. I hope my English is readible to you all...

 

Welcome to the site !!
That rust almost looks like paint, on the shoes. They don't appear to show delamination.

There's a household cleaner called CLR here in the States.
Maybe you have a bathroom liquid cleaner that removes rust stains and calcium deposits?? Do you have "Naval Jelly" ??

And your English is better than some of the Local's !

 

Haha thanks! I'm trying the best I can
It's sometimes pretty hard to understand all the technical words, but so far I can keep up.

I'll try to clean it with some sort of bathroom cleaner (we have Antikal). I also want to properly clean the thing that behind the shoes. When I want to remove the shoes I only have to remove the springs I guess?

 

Yes, and use white lithium (waterproof) grease to re-assemble the pivot points, and also clean and lube the brake pedal lever pivot.
Do everything while it's apart.
A little bearing grease on the rear wheel bearings, and on the drive splines.

Don't bother getting things too clean ! No one will know.

 

Thanks for replies/help (so far), I'll go back into the garage ;-)

EDIT:
Little trouble in understandig what 'pivot points' (probalby turning/twisting points?) are? So I uploaded a picture again
And should I put the bearing grease in the hole of my drum brake or put it on the whole axle?

Ps. I won't get 'm too clean, but better make a good start 8)

 

A set of EBC brake shoes are not that expensive only about 30 dollars in the US. Since the brakes are the most important part of any motorcycle/motor vehicle. I would put all new pads on the bike.

 

Pivot points = any and all metal-on-metal contact points, but not so much grease that road impacts would dislodge the excess.
You do not want to risk getting grease on the friction surfaces.
That is why you use white grease, it is more sticky.

The brake actuating cam has a round shaft (pivot) and also, if you remove the foot lever, that shaft needs clean/grease.

 

When you pull the shoes off its a good idea to pull the lever off mark where it was pull the pivit thru the plate. Wire wheel the shaft and aput a little grease around it also before lubing pivit points . Brake dust gets in there and sometimes makes it stick. better safe then sorry

 

That Cam which spreads the Brake Shoes, ... pulls-out from the inside.
Do a thorough cleaning of the Inside Diameter of the hole that Shaft passes through.
A tightly rolled-up section of ScotchBrite Pad will make it shine like new.

After you clean the Rotating area of the Shaft, ... put it in a vice and "Shoe-shine" a smooth finish on the area that rotates within the hole in the Rear Brake Case.

Notice that the Shaft has an "Hour Glass" shape to it.
Pack that channel with Waterproof Synthetic Grease.
That will keep the Shaft from rusting and make the Break easier to apply.

 

Welcome to the site and you'll have to upload pics of the entire bike soon. Happy riding.

 

Guys, thanks for all the info. The brakes are cleaned and greased and working! I'll soon upload some pictures of my bike (first I have to find out where haha)...

 

looking forward to seeing them Remember to resize them to 500 pixels
