Have the girls pick up a turkey baster in the housewares department at Walmart. If you do not have it, have them also get a quart of DOT 4 brake fluid from the Walmart automotive dept. You also will need a small box end wrench (probably #10) also available at Walmart.
With the turkey baster suck all of the fluid out of the master cylinder reservoirs.
Refill the reservoirs with fresh DOT 4 brake fluid.
1. Find the wrench size that fits the brake bleeder on one of the front wheels.
2. Have some one step on and hold down the brakes.
3. While they are holding down on the brake pedal, open the bleeder valve to let the fluid out and then immediately close it again.
4. Have the person release the brake pedal, wait 5 or 10 seconds and then pump on the pedal and hold down again.
5. Open and close the bleeder again to let the fluid out.
6. I would repeat the above procedure 4 or 5 times.
7. Open the master cylinder and fill it up again.
8. Go to the other front wheel and repeat steps 1 through 7 on that side.
You now have replaced the fluid in the front brakes. The front is where the heat is that boils the fluid. Do not worry about the rears. They can be done some other time.
The above should take you 15 or 20 minutes to complete in the Walmart parking lot. If you have difficulty reaching the bleeder valves, simply turn the wheels one direction or the other to give you more room.
