Flushing Brake System
 

OK, i dont know if it is typical or not, but my brake pedal seems soft. It just feels like its not going to stop the truck in time, it does stop, but not like i would think it should. I have bled the brakes, so thats not the problem.

Im going to flush the system and replace the fluid because i have no idea how old the fluid is, being that it is the fluid that was in it when i bought the truck. My question is, how would i flush the system thouroughly?

1 - master could be on the fritz

or

2 - rear brakes need adjustment

or

3 - info on flushing brakes

or

you are paranoid :)

Haha... it could be number 4... But i want to rule out the other possibilities if possible. I have never even opened up the rear brakes, so i guess that should be first. The front brakes have new pads though.

Could be the master cilynder if the pedal goes all the way down and nothing happens try this while driving at slow speed pump the pedal down few times before you step all the way if works I'm 100% sure is the master cilynder.Happened to me once.

Does it get worse when the brakes are hot?

The fastest, cleanest, most effective one-man way to bleed & flush.

I need to flush my brake system too. thanks for the info.

I will cast a vote for the Master cyl.....they are easy to rebuild though.....

Stupid question/slightly off topic.
I don't have the time or equipment with me at school to do a full brake fluid flush. Can a good brake shop place do that?

I just had to do that when I got my new/old truck home as there was almost no fluid in the system. I learned from a friend here the "quick easy cheap way" that worked perfectly, now my brakes are as good as new.
and this flushes all the crud out too.
you take 4 quart jars, 4- 2 foot long clear vinyl hoses that fit TIGHT over the bleeder, and a a few quarts of brake fluid.
pour about a half cup in each jar.
set a jar beside each wheel under the bleeder, and put the hose on the bleeder and the other ends in the jars, submerge the hoses IN the fluid, it keeps the air from going back in the system.
open the master cylinder, fill it with fluid.
slowly pump the brakes. I found doing the back wheels together first then the front works better but, to each his own way.
keep refilling the master cylinder with clean fluid.. keep pumping.
take notice of all the dirty fluid filling the jars.
after you've pumped about a quart through the system top of the MC and close the bleeders.

your done!
if they are still a bit spongy, bleed them the same way but one at a time and watch for bubbles in the jar (you'll need someone to pump the brakes for you).
My Friend helped me do it and showed me how easy this is. I couldn't believe the old fluid was so dirty.

i have rear speed bleeders, they work great... .some people sya they suck, but i never had problems with mine... they have been on my truck over a month and a half, and i drive about 400 miles a week.....

mine are russel though, got them from summit, they were pretty cheap, like $10 for 1 pair (2 wheels)

I also discovered my back self-adjusters were not self adjusting and when I manually adjusted them the brakes got firm again and it stopped a lot easier.
