Rear Drum Brake Service — 2nd Gen

Difficulty 3/51.5–3 hrs$80–3202005-2015

2nd gen Tacoma rear drums go 80,000+ miles and cost under $100 a pair in shoes, but the service is slow the first time and the two things that actually bite owners are a seized self-adjuster and a weeping wheel cylinder that contaminates brand new shoes. Do one side at a time and check the cylinder while you are in there.

Toyota kept rear drums across the entire 2005–2015 run. Drums suit a truck that spends long stretches under light braking without cooking pads, and they hold the parking brake mechanism in one tidy assembly. Most owners meet them only when something scrapes, when the parking brake stops holding on a grade, or when a brake inspection finds a drum wet with fluid.

Four distinct failures live in this assembly and they present differently:

A low or soft pedal that firms up after several pumps points at shoes sitting too far from the drum, which means the self-adjuster is not doing its job. The Tacoma's adjuster steps out when you brake in reverse; a star wheel rusted solid never extends and the shoes wear while the pedal gets longer.

A parking brake that ratchets to the top of its travel and still rolls is the same root cause plus a stretched or corroded cable. Adjust the shoes correctly first — cable adjustment on top of unadjusted shoes hides the real problem.

Grabbing, pulling to one side, or a burning smell after a highway run usually means one drum is dragging, either from a stuck wheel cylinder piston or a shoe that never released.

A soft pedal that keeps sinking under steady foot pressure, with no external leak, is a master cylinder bypassing internally, and no amount of drum work fixes it. Confirm this before ordering shoes.

Shoes are 04495-04010, about $55 for the axle set. The complete kit (04495-35230, $95) adds the hold-down pins, springs, return springs, and adjuster hardware for both sides. On a truck past 100,000 miles the original hardware is rusty and takes a set — the $40 difference is the right money, because a tired return spring is what leaves a shoe dragging after everything else was done correctly. Drums (42431-04061, ~$110 each) are only needed if the friction surface is scored past the wear limit stamped on the drum or if it has gone out of round, which shows up as a pulsing pedal at low speed. Wheel cylinders are $45 each and are cheap insurance on high-mileage trucks.

Total realistic spend: $80–110 doing shoes only with existing hardware, $150–200 with the full hardware kit and a pair of wheel cylinders, and $300+ if drums are also replaced. A shop charges $250–400 per axle for the same work.

Safety note: brakes are not the place for unbranded parts. Use Toyota shoes or a known friction brand. Never let brake fluid contact painted body panels, and never reuse fluid drained during a bleed.

Leave the opposite side fully assembled. It is your reference for spring orientation, adjuster direction, and which shoe carries the parking brake lever — and the two sides are mirror images, so the adjuster threads opposite hands. Photograph the assembly before you touch it anyway; the photo and the intact side together will resolve any question the manual leaves open.

While the drum is off, pull back the wheel cylinder boots with a screwdriver tip. Any wetness behind the boot means the seal is passing and the cylinder gets replaced now, not after it soaks a new set of shoes. Fluid-contaminated friction material cannot be cleaned and reused.

If this is the second or third shoe service on the truck and you are wading water regularly, the rear disc conversion is the alternative worth pricing, and front brake condition should be checked at the same time via the front pads and rotors guide since a dragging rear masks a tired front.

Steps

  1. Block the front wheels, loosen rear lug nuts, lift the rear axle onto stands, release the parking brake fully.
  2. Remove the wheel. Remove the two Phillips screws holding the drum to the hub — soak them with penetrant beforehand, they seize.
  3. Pull the drum. If it will not come, thread two 8mm bolts into the threaded jacking holes in the drum face and turn them evenly.
  4. If the drum is held by a worn ridge, back the adjuster off through the access slot in the backing plate before forcing it.
  5. Photograph the shoe assembly from two angles before disturbing anything.
  6. Remove the return springs, then the hold-down springs and pins, with brake spring pliers.
  7. Remove the adjuster, transfer the parking brake lever off the trailing shoe, and remove the shoes.
  8. Peel back the wheel cylinder boots and check for fluid. Replace the cylinder if wet, then plan on bleeding that corner.
  9. Clean the backing plate with brake cleaner. Grease the six raised shoe contact pads with a thin film of high-temp brake grease.
  10. Clean and free the adjuster star wheel; replace it if the threads are rusted. Anti-seize the threads lightly.
  11. Fit the parking brake lever to the new trailing shoe, then install shoes, adjuster, hold-downs, and return springs in reverse order.
  12. Turn the star wheel until the drum slides on with light, even drag.
  13. Refit the drum, Phillips screws, and wheel. Torque lugs to 83 ft-lb.
  14. Repeat on the other side, then bleed the rear circuit if any cylinder was opened.
  15. Pump the pedal until firm before moving the truck. Confirm a hard pedal at rest.
  16. Do 10–15 moderate stops in reverse in an empty lot to let the self-adjuster set, then set the parking brake on a grade to verify hold.
