Toyota Corolla Hybrid (E210) front brake pads: step by step, with the hybrid safety step
This is how to change the front brake pads on a Toyota Corolla Hybrid, the E210, step by step, with the torque settings, and the hybrid safety step most guides leave out.

Before you start: Front pads only
This is the front pads only. The fronts don't need the electric parking brake put into service mode. The rears do, so they're a different job.
Hybrid safety: Let the brake pump settle
Here's the hybrid part. The Corolla Hybrid has an electric brake pump that stores pressure in the system. So switch the car off, and close the doors. Wait about a minute, until you hear the pump run and stop.
Hybrid safety: 12-volt battery: negative off
Then disconnect the negative lead on the 12-volt battery. On the 1.8 it's under the bonnet. And don't press the brake pedal while you work.
Parts
Parts: a set of front pads, for both sides, brake cleaner, and a little anti-squeal paste.
- Front brake pads (set): Both sides, by registration
- Brake cleaner: Disc and carrier
- Anti-squeal paste: Pad backs only
Tools
Tools: a 21 millimetre wheel socket, a 14 millimetre socket for the caliper, a piston wind-back tool, a torque wrench, a wire brush, and axle stands.
- Sockets: 21 mm wheel · 14 mm caliper
- Wind-back tool + torque wrench: Piston, and every bolt
- Wire brush: Carrier and pad slots
- Axle stands: Never just a jack
Safety: Chock, loosen, lift
Chock the rear wheels. Loosen the wheel nuts with the car on the ground, then lift the front and set it on axle stands.
Step 1: Wheel off
Take off the wheel nuts and the wheel. Hold the wheel as the last nut comes off.
Step 2: Caliper off, tied up
Clean the two slide pin bolts at the back of the caliper, and undo them with the 14 millimetre socket. Lift the caliper off, and tie it up. Never let it hang on the brake hose.
Step 3: Old pads out, check the disc
Take out the old pads. Check the disc. The minimum thickness is stamped on it, usually 19 millimetres on this car. If it's thinner, or badly worn, fit new discs as well.
Step 4: Clean the carrier
Clean the carrier where the pads sit with the wire brush and brake cleaner. Put a thin layer of anti-squeal paste on the pad backs, never on the friction side.
Step 5: Push the piston back
Clean the caliper piston, then push it back in slowly with the wind-back tool. The fluid in the reservoir will rise as it goes back, so don't let it overflow.
Step 6: New pads, caliper back on
Fit the new pads, refit the caliper, and tighten the slide pin bolts to 35 newton metres. Some manuals say 34.
Step 7: Wheel on, torque it
Spray the disc clean with brake cleaner. Refit the wheel, lower the car, and tighten the wheel nuts across in a star, to 103 newton metres.
Step 8: Pedal firm before you move
With the battery still off, press the pedal a few times to bring the pistons out. Reconnect the battery. The pump will run: leave the pedal alone until it stops. Then press it again. It must feel firm before the car moves. Check the fluid level.
Afterwards: Other side, then go easy
Do the other side the same way. Take it easy for the first 150 to 200 kilometres, while the new pads bed in.
Figures and where they come from
Every figure in this guide is checked against at least two independent sources. Where sources disagree, we say so.
- Corolla Hybrid brakes use an electric brake booster pump with an accumulator that holds pressure; switch the power off before work.
