2009 Tacoma Rear Brakes Adjust - Need Directions

At my 15,000 mile oil change the dealer said the rear brakes need adjustment. I said I would do it myself. Can someone tell me how or lead me to a link that shows how? I did a search and did not find any good directions.
Vehicle is a 2009 Tacoma.

 

they should self adjust just by backing up quick and hiting the breaks hard a couple of times.

 

x2...drums are typically self-adjusting. You don't necessarily need go fast, but roll backward slowly and apply the brakes. This forces the adjustor to tighten down onto the drum. If you attempt to manually adjust them by turning the adjustor yourself, you may actually tighten the shoes down on the drum which would be applying your brakes all the time...long story short, just use the auto adjustor.

Get yourself the Haynes manual or check out:

 

sounds like a classic case of an upsell... if you want to do it manually without overtightening, jack up the rear end, put the truck in neutral, tighten the adjuster till you feel a drag on the wheel (or hear the shoes contacting the drum) while turning it, then back off just until the drag goes away. or check the fsm ^

 

The adjuster is accessed from under the truck looking at where the axle meets the wheel. There will be an oval shaped rubber plug near where the brake line goes into the wheel cylinder. Remove the plug to access the adjuster.

 

Are the shoes still in good repair?

The drums are self adjusting, however - you should open up the drums and make sure the shoes are in good shape & wearing evenly. If you have a lot of dirt/mud packed in there, you need to clean it out. If you have a lot of mud/dirt packed in there, the adjusters might be packed with dirt and can't adjust things properly.

 

Thanks for the replies. I'll try the back up and apply brakes method first. By the way the brakes work fine.
I have always done my own maintenance on older cars. I asked the dealer service writer if there was an adjuster ratchet like older cars and he said no.

 

I checked the FSM link. I did not see one for the 2009 Tacoma. Does one of the earlier ones apply?

 

ttylerr is right... drum brakes are drum brakes.... tighten them down until the drum drags and then back it off a little. Good to go.

 

Most things are identical 2005-2011, especially basic mechanical systems.
