Newby here and have been reading the brake threads and trying to relate to my vehicle situation.
My new front brakes won't lock up on dry pavement but they will on gravel. This has been an issue since before the brake work. The pedal travels a bit further than my other cars. My main diversion from stock configuration is going from tire size 225/75/16 to 245/85/16. I don't see much talk about larger tires on the brake threads.
I wonder if the tire size increase is too much for my cheap W/T brakes?
I might have even blown my master cylinder seals trying to get the fronts to lock up because during testing it started getting wet between the booster and master so I replaced with a rebuilt master.
Truck is 1991 K1500 W/T standard cab (probably tiny cheap brakes). The booster is 9" diameter. The truck is OBD1 and has the RWAL brakes in the rear.
I read the sticky'd thread above about brake upgrades and saw light duty 3/4 ton front calipers can be used in my situation. Would this help any?
When shopping at autozone they showed a larger diameter booster (10-1/2") that is supposed to fit. Will it work or help any? I am a bit concerned more boost might blow my master cylinder seals again. I had a 20% off and free shipping coupon and the 10-1/2" is also $40 less than the 9" so I ordered the 10-1/2" already.
I would pull my new 1/2 ton calipers and do the 3/4 ton upgrade next if it helps a lot. Then try the booster.
Any help is appreciated...
