Ive got a 97 2wd F150 with 98,300 miles on it. Ive always been great with changing the front discs but I was wanting some feedback on how long to go before changing the back ones. Im getting a rough jumpy slow down when I hit the brakes whether its hard or soft. I already now rotors can cause this but the front rotors are perfect. Lemme know if anybody has suggestions. Thanks...j.g.

 

It's pretty easy, your drums are probably frozen on so the best way to get them off is to hit inbetween each lug 10 times, then move on to the next set of lugs, and then the next. It will pop right off. And with almost 100K on the clock, it'd be a good idea to replace them.

 

Hey Connexion,

how jumpy is jumpy?

My 99 has started to clunk when I slow down. At first I thought it was a transmission thing from downshifitng (automatic) to a stop. But after braking with the truck in N it still clunks (just once and not all the time). I can feel the brake pedal react to this clunk and I even hear the ABS compressor start to chatter. Any similarities to your situation?

Anyone else outthere got any ideas?

Also when I check the drums the pass side drum is a lot warmer that the drivers side.

 

slipknot you might have a bad cylinder back there. pull it off and inspect it (clean it while its off, just a can of BPC)

connexion, you don't have to replace them until they are bad. They can even be turned just like front rotors if there is slight grooving. The only time I ever saw rear drums cause something like that is when one of my guys over tightened a rear and warped the drums in less than a mile. Otherwise, check clean and adjust them if they are still beefy with life left and drive again. And use a micrometer to check the front. Check them in several places all the way around. You'd be suprised how fast they can get shot in the azz.

 

Drums are a lot more forgiving to runout and wear than rotors are. Only time I really replace drums is if the shoes hit metal to metal or hardware breaks and cuts deeply into the drums.

 

98 navi,
you talkin about a wheel cylinder? explain if you dont mind

ive done discs but never drums before.

 

I'm going to be doing my drums next week as well.

I don't know if you know this or not, but make sure to get a hardware kit for them as well. Its a new set of springs that hold the shoes in place; they get worn out over time.

I bought new drums; I figured that after 6 years and 70k miles, I might as well get new ones.
