72 K5 Brakes (HARD) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Artiep92 · 02-05-2015, 03:29 PM

So, I've been working on my brakes on my Blazer(DRUM&DISC) on and off for about 2 years now and still have a hard pedal. The break pedal is hard. I hit the brakes and it stops, but it still continues to roll a bit.
I have checked the brake lines and they are good. I then replaced the brake booster and master cylinder and the pedal is still hard.
I just replaced the calipers and the pedal is still hard.
Could it be the perportioning valve? That is what I may replace next.
I have talked to other friends with first gen blazers and they say that the brakes on their blazer are okay, but not great.
Anyone have any suggestions?
How do your guys blazers stop? Do the brakes lock up the tires?
