my brakes on my silverado 1500 feel spongy, but when i take off my tires i have almost full pads. anybody know of any ideas of what is wrong. i also heard a rumor that 99' 1500's had spongy brakes from the factory??

 

was gonna say I havent drivin many 99-2000-1998s and the like that dont have spongy brakes.....

 

Hows the rear brakes look? are they disk or drum? You may try to adjust the shoes up on drum brakes to take up slack and pedal travel. Look at the back of the master clynder, is it leaking? maybe getting air in the system from a bad seal. Then how does the brake fluid look? Is it black and dirty? If so flush the old fluid out. Suck up the fluid out of the resivor, then clean the resivor good, add freash fluid, and bleed the brakes out till new fluid comes out of the bleeders. Give that a shot.

 

well my 99 does the same thing....i just got used to it really...i have some new pads also

 

they are disk brakes

 

Make sure when you pull the tires off the bleeders are tight & the calipers are dry & not leeaking . Rarely enough you may have a slightly torn piston boot That makes the spongy feel . I recently had both my rear cylinders blow out .It started with the spongy brakes & low fluid Just a thought anythings worth a try were all in this together helping each other
