one more thing to check. There is a push rod between the booster and the MC piston. The rod is adjustable. When you change MCs you have to adjust the push rod because the piston socket depth is different between the 7/8 MC and the 15/16 MC. Look it up. If the push rod is adjusted too long the brakes will lock up because the longer push rod prevents the piston from retracting all the way which blocks the fluid return port inside the MC. This will result in your brakes locking up after a few stops. If this happens while road testing just open the MC bleed screws and limp home and readjust the push rod. If the push rod is too short you will experience a long pedal because the piston is not pushed far enough to fully engage the brakes. That is, the piston is not pushing enough fluid. Your brakes will feel mushy and you will experience a pedal with long travel before engaging the piston Do a search for push rod adjustment. It is critical to properly functioning brakes and brake feel.

Do your speed bleeders work with your Motive power bleeder ?

Yep, p/n 639560 for the front calipers https://www.ebay.com/itm/Russell-Brake-Caliper-Speed-Bleeders-Front-Rear-for-1970-1973-Datsun-240Z-/192230009783

Edit Earl's speed bleeders from Summit. They come in several lengths. https://www.summitracing.com/search/product-line/earls-performance-solo-bleed-brake-bleeders?N=4294909157

See my last post. If you gutted the PV you may have now tied the front and rear brake circuits together which would explain fluid flowing between the tanks.

You gutted the OEM proportioning valve? The 240Z PV can be gutted as it only effects the rear brake circuit. Not sure about the 260Z and 280Z PVs, but you may have just tied the front and back hydraulic circuits together. Somebody chime in on this.

^^Yep ^^ Like this.....................................

Bench bleed the MC properly and repost. I Assume you installed a 15/16 or 1 inch MC.

I have swapped the 240z push rod with clevis into the Tilton/Wilwood MC. There is a snap ring that holds the rod in place.

No

Look at the rocker inside the TS switch in the video. See the center stalk that pushes the rockers? There should be a small ball bearing with a spring in the center stalk.

Jegs, Summit and Speedway show a brake booster clevis 3/8-24 thread. Not sure of thread type for the 240Z/280Z. They also sell push rod extension kits. I seem to recall (10 years ago) that the 240Z and 280s push rods were of different diameters and he clevis pins were different . When I swapped in a 280Z booster into my 240Z I swapped the 240Z push rod into the 280Z booster so I could use the 240Z clevis. My pedal has some slack, but the clevis is adjusted all the way out. If you find a way to lengthen the clevis post your solution here.

Very quiet inside. Depends on interior insulation and muffler choice. No problems in ten years. WOT is very loud. But I seldom use WOT. Video:

What year 240Z, 260Z, 280Z? Topic has been covered extensively. Search the forums. Could be the combination/turn signal switch. Suggest that you search "turn signal switch repair" etc. Could be a simple loose wire or burned out bulb. Down load the electrical schematic for your car (available here or at other websites). https://www.youtube.com/watch?v=exeIsC70F_o https://fiddlingwithzcars.wordpress.com/2012/12/04/turn-signal-repair/ https://www.classiczcars.com/forums/topic/34330-72-240z-turn-signal-stoped-workining/ https://fiddlingwithzcars.wordpress.com/2013/01/20/hazard-switch-brake-light-turn-signal-circuit-analysis/

Check out the rear springs, take some pictures, and post your findings here. The previous owner may have cut the springs, installed softer, or progressive rate, springs etc. At some point you may want to rebuild/upgrade the stock suspension: shocks, springs, polyurethane bushings, insulators etc. Makes for a huge improvement in handling and ride. Recommend stiffer springs that maintain stock ride height for a street car. The 240Z is low enough.

Confirm that the connections on the ballast resistor, coil and distributor are clean and snug.

Not sure how you arrived at Toyota front and back. Won't work. The Toyota calipers only go on the front because they have no parking brake function. The 240SX calipers have a parking brake function. So they only go on the back.

Yep. It is possible that having the car on jack stands may be twisting the body. Another possibility is that the car has been in a wreck in the past. Try putting the car on the ground and test fit the part. Also, post pictures of where the part isn't fitting etc
