Q: Brake issues

asked by on July 20, 2016

Hello, I recently changed all of the following on my 2003 Silverado 1500, master cylinder, vacuum brake booster, vacuum hose from booster to the back of the block, brake pads and rotors, calipers, and brake hoses from the caliper to the metal line, bled almost 2 gallons of brake fluid through the system to get out all the air from the lines, I watched video on YouTube about purging abs pump but my scanner isn't able to perform the purge, when I apply the brakes quickly my truck doesn't stop on a dime like it use to, if I pump the brake peddle 3-4 times it gets hard and I'm able to stop, please help I don't know what else to do and can't afford to take it to the dealer or mechanic shop. Thanks for your time
