  Q: How to service and repair the Clutch Master Cylinder on Toyota Tundra?

  A:

  You need to start Clutch Master Cylinder service by taking out the filler cap and float from the reservoir followed by syringe-drawout of brake fluid while keeping all painted surfaces free of fluid residue. The clutch line needs removal from the master cylinder through the use of Special Service Tool: 09023-00100 while a container collects the fluid. Use needle-nose pliers to remove first the clip combined with clevis pin followed by clevis pin combined with wave washer. Begin by taking out the master cylinder by removing its two mounting nuts followed by pulling it out before removing the gasket. To access the reservoir tank disassemble by driving out its slotted spring pin with a pin punch and hammer before extracting the reservoir tank together with its grommet. The initial step involves loosening the lock nut to extract the clevis with boot before pushing the push rod under snap ring plier guidance to eliminate the snap ring and follow with push rod and washer removal. Remove the piston with spring. Reassembly begins with applying lithium soap base glycol grease coating then the piston with spring needs to be inserted into the cylinder followed by installing the push rod and boot while setting the washer onto the push rod and using snap ring pliers to set the snap ring. Install the lock nut and clevis firstly before you place the reservoir with new grommet and place the slotted spring pin inside. A new gasket goes first followed by mounting the master cylinder with two nuts and torquing them to 14 Nm (143 kgf-cm, 10 ft. lbs.). The clutch line installation requires Special Service Tool: 09023-00100 that needs to be tightened to 15 Nm (155 kgf-cm, 11 ft. lbs.). The clevis pin alongside its wave washer and clip must be installed before filling the clutch reservoir with brake fluid to proceed with bleeding the clutch system followed by clutch pedal adjustment and leak inspection.
