- 1Large C-clampPushes the caliper piston back for the new pads.Amazon
First time? Watch for these
- Do one side at a time, so the other side shows you how the clips and pads go back.
- Pushing the piston back raises the brake fluid: watch the reservoir so it doesn’t spill. Brake fluid eats paint; wipe drips right away.
- Before you drive, pump the brake pedal until it’s firm. The first push after new pads can go all the way down.

First time? Watch for these
- Do one side at a time, so the other side shows you how the clips and pads go back.
- Pushing the piston back raises the brake fluid: watch the reservoir so it doesn’t spill. Brake fluid eats paint; wipe drips right away.
- Before you drive, pump the brake pedal until it’s firm. The first push after new pads can go all the way down.
- With an electric parking brake, put it in service mode first (owner’s manual or a scan tool). Forcing the piston breaks the motor.
Battery replacement
Parts
- 112-volt batterySame group size as the old one (on its label)Amazon
Supplies
- 1 boxNitrile glovesNegative (−) off first, back on last.Amazon
First time? Watch for these
- Don’t let a wrench touch both posts, or a post and the car body, at the same time: it sparks.
- Tighten the hold-down so the new battery can’t move.
- Take the old battery back to the store. Most charge a core fee until you do.
- Some cars need the radio code or the power windows reset after. Your owner’s manual says how.
Cabin air filter
Parts
- 1Cabin air filterNot the engine air filter. The arrow on its edge shows airflow.Amazon
Tools
- No tools on most cars
First time? Watch for these
- On many cars it sits behind the glove box: empty the glove box, then unhook its stops so it swings down.
- Put the new filter in with its arrow pointing the same way as the old one’s.
Wiper blades
Parts
- 1 pairWiper bladesDriver and passenger sizes differ on most carsAmazon
Tools
- No tools needed
First time? Watch for these
- Lay a towel on the glass. A bare wiper arm can snap back and crack the windshield.
- Listen for the click when the new blade locks onto the arm, then run the wipers once to check.
