Rear drum brakes - how many miles are you getting

Not sure if serious. Your E-brake does adjust the rear drums. You should use it every now and again to keep the shoes adjusted.

 

No and No.

The rear brakes work all the time for parking brake and normal braking.

302, Some of your comments and your avatar disturb me...

 

Thank you, your avatar doesn't disturb me at all. When you hit the E-brake, which brakes work? I am serious, I thought the rears were E-brake only. I'm doing a front brake replacement today, hence my inquistion.

On the Tacoma the Parking Brake ( or E Brake ) only uses one shoe on each side of the rear brakes. It has a cable that pulls a lever inside the drum and moves the primary ( rear most brake shoe ) against the drum which holds the wheel from turning.

Vehicles with Rear Disc Brakes have dedicated parking brake that is only used for parking. The rear disc or service brakes are a separate system as you were saying.

 

Not all rear disk brakes have different parking brake systems a great deal use the same pad as the breaking system.

 

I had the same squeaking issue for a while in my 18' SR w/ rear drums... Whole thread about it below:

Turns out, I had a bad wheel cylinder. I agree w/ others and recommend diagnosing/troubleshooting in this sequence from simplest to most involved:

1 - Pull drums and visually inspect for debris wedged in the backing plate
2 - Give everything a good spray-down w/ brake cleaner and sand down contact surfaces on the backing plate
3 - Small bit of grease at shoe bearing points on backing plate (3) on 3rd gen.
4 - Visually inspect hardware for broken or twisted spring making contact w/ backing plate
5 - Lightly sand rotors to knock-off any glazing
6 - Swap drums from Left to Right side of truck
7 - Have someone in the cab lightly depress the brake to ensure wheel cylinders are pushing both shoes outwards
8 - Bleed brake lines to ensure no rust or debris preventing proper wheel cylinder expansion
9 - Replace backing plate (first component to rust)
10 - Replace drum shoes/hardware
11 - Turn or replace drums
