I am thinking to change my brake fluid to Valvoline Synpower.
I think it's just need take all the old fluid out and put the new fluid into the car and pump the air out. but someone told me that if I let the system empty(no fluid) there will be something wrong the ABS. is that true? cause I don't have the service manual could anybody tell me the step to change the brake fluid?

thx a lot

 

It wont hurt the abs if you let all of the brake fluid out.
You must clean the brake master cylinder thoroughly if there is any dirt in it.
If any of that dirt gets down past the master cylinder seals.
It could cause the seal to tear, causing brake master cylinder failure. (pedal to floor/no brakes).
Do not push the brake pedal all the way to the floor.
If there is any dirt/corrosion (usually near the end of the pedal travel) it can also damage the brake master cylinder seals.
Just remove the old brake fluid from the master cylinder.
Add the new fluid and bleed the brakes.
Get a bottle and a short hose.
Put the hose into the bottle.
Add just enough brake fluid to submerge the hose.
Then go to the first wheel caliper.
Put the hose onto the bleeder screw and crack the bleeder screw open.
Then you can let the bottle sit, while you pump the brakes.
When the pedal is depressed it pushes fluid out.
When the pedal is released the master cylinder sucks fluid back into master cylinder; out of the reservoir.
Then after about 20 pumps (down then up).
Close the bleeder, wipe of any brake fluid and go to the next wheel.
Helm states a different procedure than I am typing below.
I have done it both ways at work (EARNHARDT HONDA).
You will get the same result, using either method!
I was taught the way shown below.
Start at the farthest wheel from the brake master.
Then work your way back to the closest wheel.
So right rear, left rear, right front, left front.
Then take it out for a good brake check (panic stop, to make abs cycle).

The Helms service manual says to start with the front left then work clockwise: FL, FR, RR, LR. Curious, where are you getting your info from Cesar??

I'm not sure about the whole ABS thing owen. However, if you do a search on "brake bleed" something relevant will most likely pop up.

<edit> something relevant to helping you bleed and flush your brakes. Not sure about the ABS thing popping up though in that search <edit>

 

so it's just like regular fluid changing?

oh btw why change stainless steel brake line? safety?

 

You are best off to not allow air into the system if you can avoid it. Open the bleeder valves one at a time and refill the reservior as it goes down to avoid it running dry.

 

Easy on the caps bro

 

haha i cant believe you found a picture for that

about the brakes... i'd like to know how most people change their fluid as well

 

As you bleed the brake system and refill the master cylinder, the old fluid will be replaced by the new fluid. If you do this long enough, (10-15 minutes) eventually you will have flushed the system. I like to remove the old dirty fluid from the master cylinder before I start the process. Otherwise, dirty fluid will be cycled through the system.

One way to remove the old fluid from the master cylinder is to use a syringe or a turkey baster. Whatever you do Owen, try not to spill brake fluid on your paint. Brake fluid will eat through paint VERY quickly. Place a lot of paper towels around the master cylinder when re-filling the master cylinder. Maybe put a thick towel over the fender just in case a drop falls out of the turkey baster. When I remove the turkey baster from the master cylinder, I plug the bottom of it with a wad of paper towels otherwise it will probably drip.

I hope you are familiar with the bleeding process Owen. If not, let us know.

 

Somebody used that on me when I first registered for this site. That was before I became internet savvy

If nobody chimes in, I will post details later. I need to take a rest.

 

just because went to the Thunderhill track evnet this Monday, and after 6 session 2 hours track time, damn the brake is hot, the rotor pad and fluid, even the rims are over 100' and after 3 session, the brake is hard to stop the car as well. I don't want spend too much money to upgrade the whole system at this time(but I do really like the ENDLESS), since the brake pads need to change, I will go drill the rotor and change better pads and maybe brake line, of course the fluid.
I bought the fliud before the event and tried to change it, but just heard somebody told me that might hurt the ABS, so just asking you guys before doing that.
thx a lot for helping me here guys.....
