Clutch Dampener 2010/03/09

Posted by Michael in my IS300.

In the stock clutch hydraulic line, there is a Clutch Dampener Device (CDD).  This device acts as a flow restrictor when releasing the clutch pedal (engaging the clutch) but offers unrestricted flow when pressing the clutch pedal.

The design intent of this is presumably to soften the engagement of the clutch and contribute to some sort of Lexus luxury.  It is not effective for someone who prefers to feel more connected to the mechanics of the car.  Eliminating the effect is simple; disassemble the CDD and remove the flow restrictor components.  Below is a picture of the CDD disassembled.

The CDD is located on the driver side near the firewall.  Just follow the clutch hydraulic line from the reservoir.
