I drive a Peugeot 406 (D8) with XU10J4R 2 litres 16V engine with a 4HP20 gearbox.

My Brake Pressure Regulator/compensator (device between the rear wheels) is leaking.


Does anyone know if there are any repair kits available for it, or if it is repairable. If no repair kit is available for sale, then can the parts like seals and o-rings be easily obtainable ?

Does anyone have instruction manual on how to do the Setting after it has been removed and reinstalled ?
