FYI - Brake Fluid Flushing

[jelag]

I just pulled the wheels and did rear brakes on my 05 - 3500 dually. Front brakes are still 25% but I have to admit that I'm tardy in taking care of this truck... I ran 16 oz of brake fluid through each caliper with my vac pump and container. That's 2 quarts total and to be honest I'm surprised that I'm still not seeing clear brake fluid at the caliper. . the fluid catch container measures the contaminated fluid... . I'm very happy that the dust boots on the calipers were in good shape... This truck has got 135K miles and we tow a 15K lb trailer about 85% of the time.....



I guess more than anything I'm unhappy with myself that I've let go the past 3 years with out changing the brake fluid... This truck has a pacbrake on it and I'm careful and attempt to not use the service brakes over 40 mph... so I'm pleased with the brake pad life. .



I guess that I'm also saying that I'm going to move from a 3 year fluid change to a 2 year change and see where that takes me...



I've been using software from http://www.carcaresoftware.com/ for at least 15 years now and have tracked almost everything to all the trucks, trailers etc...



Pull the cap off your master cylinder and take a look... my next project is my jeep before we head south to AZ for the winter...



Just my thoughts...

Just replaced my rear brakes because the calipers hung up and destroyed everything. Changed the fluid at that time, I let mine go too long as well.

Changed my brake fluid around 100K. It was dark, but, after a few pumps on the pedal it came out light & clear at each wheel. Used about 3 pints total. Will do again this year. Too easy & cheap not to do. Also did the PS fluid around 90K. Dark & burnt smelling. Need to do it again soon. 150K on truck now.

When you guys pushed your calipers back, did you crack the bleeders before? That's a good way to move fluid.
