I just got a 99 tacoma v6 5spd 4x4 a few weeks ago. The rear passenger brakes are over adjusting and causing the drum and rim to get hot. I have replaced the drum, brake shoes, all the internal hardware (springs, horseshoe clamps etc), and the automatic adjuster. The brakes are still over adjusting and heating up the drum going down the road. It takes a few days to happen, pretty sure its from engaging the handbrake and the brakes just don't stop adjusting. The last thing to replace is the bell crank actuator. Being from Hawaii there aren't any on island and it'll take a while for the part to come in. I thought id ask you guys if anyone has had this problem or knows of a solution before I spend more money on something that will not fix my problem. The undercarriage is rusty because the PO took the truck to the beach and didn't rinse the truck down. Please help!
I've had the same problem since I replaced the brake shoes on my 1998 Limited. Although it doesn't do it as much anymore I'm not satisfied that I eliminated the problem. If it happens again I will buy Genuine Toyota brake shoes (I used OReilly shoes this last time).
Periodically and at interstate speeds, a vibration would slowly come and then over 3 to 4 miles, slowly go away. If I carefully pulled on the E-brake lever the vibration would get really bad. One time I noticed that one of the rims was too hot to touch. I backed off that brake's adjustment and that seems to have cured the heat problem, but I'm still not satisfied with the action of the E-brake (hafta pull pretty hard before it will engage).
I checked my bellcranks behind the backing plates and they are working fine. Also, the adjustment there is spot-on.
So I would recommend that you replace your shoes with Toyota parts - they're not that much more expensive than OReilly's or Autozone's.
