Product Overview
Power-steering fluid at the booster, a wet pushrod area, or seepage between the hydroboost and master cylinder may come from serviceable seals. This compact kit is for a confirmed external leak where the shaft, bore, accumulator, spool valve, and housing remain reusable.
Hydroboost repair affects steering-assisted braking and demands careful diagnosis. The kit is not a complete rebuild and does not fit every booster made by those brands. Match the unit design, seal dimensions, and 2771004 before disassembly.
