Changing brake fluid HELP needed
07/11/10 at 12:56:23

All I've ever done is top the brake fluid off when changing out my front brakes. Well its past time for the brake fluid to be drained and replaced with new.

So I went to the Clymers, checked ye olde owners manual and looked at our Savage CD. But I cannot figure a few things out.

1. I dont have the "brake pump" thingy to bleed the fluid.
The manual method described in Clymers says "hold brake lever in, AND tighten bolt 1/2" etc"

Ummm...I cannot reach like that. I have only two hands and they are attached to short arms. Can I use a rubber band to hold the brake lever or does it need squeezed as the bolt is adjusted?

2. I think, looking at the pics, I need a hose to go from the cylinder to an empty bottle to drain the old fluid. Can I use a rubber hose (soft, flexible, and on hand) or does it have to be something different due to the corrosive fluid?

3. I am confused by Clymers instructions on draining - do you keep moving/turning the bolt? How do you know when to turn it at all? My guess was turn it to start draining, then turn it back, which ties into the brake lever question - when do you do THAT?

Of course, this HAS to be done today, my one day off because I ride daily to work....! Help!

changing the fluid is easy.
1st get a rubber hose to fit over the nipple on the brake bleeder and stick it into a cup.
if you don't have one laying around, you can use the battery vent tube, blow it out 1st.
2nd, remove the master cylinder cover, have a rag on hand, that stuff eats paint.
3rd, open the brake bleeder and grab a beverage.
4th, keep an eye on the fluid level, when it gets low, refill it. don't let it suck air. when you've gone thru about half a small can, you're done.
5th, close off the bleeder and check your brake. if it's spongy, you'll need to bleed it.

bleeding the brakes.
set up as before, cover off, tube on bleeder in cup.
kneel on the left side of the front tire, right arm on a wrench on the bleeder, left reaching up to squeeze the lever.
bleeder should be broken loose but not open.

squeeze the lever, then open the bleeder.
squeeze down to the grip then close the bleeder.

repeat, checking lever feel every so often.
don't forget to refill the master.

Geez V-man that was a great easy to understand explaination!

THANK YOU!

Why can't the manuals be written like this - sheesh I was getting a headache trying to figure Clymers out.

Okay, I am out to work on this - any guess as to the nut coming off anytime soon? Whenever I start a new project on the Suzi, I am always dealing with factory-tight nuts & bolts that frustrate me into banging things around. Tongue

Repair manuals ar usually meant for peoples who already have a good understanding of how bikes work. And they usually include their way of doing it that is not the only way and they tend to leave out alot of important details. If your into doing all the work on your bike it suggest getting a basic beginners book on motorcycle maintenance that has pictures and lamens language to get the basics of how everything works. Then the only thing you need the manual for is torque specs and wiring diagrams, electrical resistances and voltages, clearances and maintenance schedules.

Or you can just on here..

Well I just finished the fluid flush & change out - 20 minutes tops ~ PISH ~ it was so easy!

I guess I just needed a morale boost to get thru it Wink

I've had to replace the brakes twice on my 2006. At those times I just topped off the brake fluid.

This is the first time I flushed it and replaced. The fluid in there was coffee coloured and the brake lever had gone soft this past week. Brake lever is now tight, fluid clear, all good for this weeks daily commute.

THANKS!

Yes, this site has ALWAYS been a huge help to me when it comes to maintenance and troubleshooting.

In particular the step-by-step with photos of basic things like the oil change and front brake change. It sooo much easier when it broken down for me with pictures. I am not so good with just written, and worse with techie manual writing.

And of course the pep club of "yes you CAN do it" that is here too.

The worry is that it will absorb water And rust out the lines eventually or in more complex systems possible crud can gum up solenoid valves.

He had never changed his fluid & it was a mess in there.

an RV with no brakes sounds like a good way to ruin the family vacation.

It makes sense to me that if enough water is absorbed in the brake fluid, then going down a mountain will be enough to boil the water at the caliper, turning the brakes into spongy nothing until they cool off, long after the impact at the bottom of the scenic overlook.

Perhaps the steam would blow past the piston, or water corrosion would screw up the sealing, but either way the brakes would not work right when you really want them to.

Somebody posted fluid changing instructions here 3-4 months ago - it was easy and slow fun.
