Clutch pedal goes to floor Honda Civic

2007 honda civic si

My clutch is really easy to push down when downshifting and it also wont go into gear when downshifting.It is a 2007 Honds Civic Si.

Typically this is caused by a failing clutch slave/master cylinder going out. A quick test would be to check the shifting with the engine off. Being able to upshift and down shift with the engine off allows you to know the syncros and trans are OK. An indication that the issue is with the clutch performance system. I would recommend replacing both the clutch master cylinder and clutch slave cylinder at the same time. You may find the need to bleed the clutch hydraulic system so i have added that procedure below. Looked up the clutch master cylinder and clutch slave cylinder for your 2007 Honda Si 2.0L:


Warning: Wear eye protection. Wear standard industrial rubber gloves.
Dismantle and inspect inside cylinder before purchasing rebuild kit. If pitting or scoring exist replace clutch master cylinder.

  1. Drain clutch hydraulic system.
  2. Remove clutch master cylinder from vehicle.
  3. Remove hydraulic fluid reservoir from master cylinder if equipped.
  4. Pull back rubber boot. There is no need to unscrew clevis from push rod. This saves you from having to adjust linkage.
  5. Remove snap ring holding push rod/washer in place using a suitable set of snap ring pliers.
  6. Pull out piston/spring assembly. You may have to use compressed air to assist in removal.
  7. Clean inside and outside of cylinder with denatured alcohol or fresh brake fluid. If you notice any pits or scrapes in cylinder, you will need to replace it with a new one.
  8. Lubricate new piston O-rings, with suitable lithium base grease.
  9. Slide assembly into cylinder.
  10. Pack end of piston, where push rod will rest and pivot, with suitable grease.
  11. Attach snap ring in place using snap ring pliers.
  12. Replace rubber boot.
  13. Replace reservoir with new copper crush washers, if equipped.
  14. Reverse procedure to install, note following:
    a. Fill and bleed clutch system.
    b. Inspect for hydraulic fluid leaks.
    c. Ensure clutch operates correctly.


Do not reuse the drained fluid. Always use Honda DOT 3 Brake Fluid from an unopened container. Using a non-Honda brake fluid can cause corrosion and shorten the life of the system.
Do not mix different brands of brake fluid; they may not be compatible.
Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
Do not spill brake fluid on the vehicle; it may damage the paint or plastic. If brake fluid does contact the paint or plastic, wash it off immediately with water.
It may be necessary to limit the movement of the release fork with a block of wood to remove all the air from the system.
Use fender covers to avoid damaging painted surfaces.

  1. Be sure brake fluid level in clutch reservoir (A) is at MAX (upper) level line (B). Fig. 1.
  2. Attach one end of a clear tube to bleeder screw (A), and put other end into a container. Loosen bleeder screw to allow air to escape from system. Fig. 2.
  3. Be sure there is an adequate supply of fluid in reservoir, then slowly push clutch pedal completely down. Before releasing pedal, have an assistant temporarily tighten bleeder screw. Loosen bleeder screw, and push clutch pedal down again. Repeat this step until no more bubbles appear at clear tube. Be sure fluid level on reservoir does not go below MIN.
  4. Tighten bleeder screw securely.
