Its design works whether the caliper is mounted on the vehicle or removed and hanging free, giving technicians and DIYers a dependable option for modern multi-piston brake systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Lisle 29100 compress all four pistons at once?\u003c\/h3\u003e\n\u003cp\u003eThe 29100 uses a multi-point plate that aligns with quad-piston calipers to apply even pressure across piston faces. Instead of rotating plates or single-point screw compressors, this tool forces pistons back uniformly to reduce the risk of uneven piston travel or seal damage.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSimultaneously compresses up to four pistons on quad piston applications\u003c\/li\u003e\n  \u003cli\u003eTool plates are fixed and do not rotate for consistent alignment\u003c\/li\u003e\n  \u003cli\u003eSpreads brake pads 2-1\/2 inches to clear pad surface for installation\u003c\/li\u003e\n  \u003cli\u003ePatented mechanism (US Patent 6,874,217) for controlled piston retact\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use the pad spreader with the caliper still on the vehicle?\u003c\/h3\u003e\n\u003cp\u003eYes—this tool was designed for in-vehicle use as well as when the caliper is removed.
