hi,i was wondering if anyone could help me out with this.Is the master pump and brake booster or servo assembly from a ucf21 ls400 compatible with the earlier ucf10/11 ls400?

You can go to Sewellparts.com and look up the part numbers for each. If they're different, I wouldn't chance it considering they're brake components... I doubt they're the same.

very unlikely.

they look the same in the parts pics in sewell.the only diff being the master cylinder of the ucf21 bolting on the booster using 2 screws whereas the ucf10/11 using a 3 screw master cylinder bolt pattern.the rear looks the same.i cant seem to check the brake booster part number for the ucf10/11.i dont think its available or mayb they're actually interchangeable.can anyone confirm this?

I have already upgraded my ucf10 ls400 discs and caliper to that from the ucf20/21 if this helps at all.mine was on the stock single of twin pot set up previously.

much appreciated.thanks
