Description:
This brake caliper piston spreader from TUTOOLS is a ratchet-style press designed to make retracting caliper pistons quicker and less awkward during brake jobs. It suits single, dual and quad-piston calipers and helps keep piston movement even while you prepare pads or service the braking system.
Key Points
The tool includes two extra steel plates that measure 4-5/8 inches long by 2-3/8 inches high, giving more surface area to press pistons without digging into the caliper. Its ratchet mechanism allows gradual, controlled retraction so you can align both sides of the disperser and force the plates evenly. According to the manufacturer, you need at least 1.5 inches of clearance between the caliper lip and the piston to fit the spreader properly. For tighter spaces, a C-clamp can be used as an auxiliary clamp during setup. ⚙️
Technical Specifications
- Name: TUTOOLS Brake Caliper Press Ratchet
- Additional plates size: 4-5/8 in x 2-3/8 in
- Material: Steel plates and ratchet mechanism
- Required clearance: 1.5 in minimum between caliper edge and piston
- Included accessories: 2 extra steel plates
Usage Recommendations
Place the two plates on opposite sides of the piston and align them so force distributes evenly across the caliper. Because the tool uses a ratchet, both extension plates must be pressured simultaneously to engage the ratchet. Tighten the plates through the initial turns until the spreader is seated, then use the switch or ratchet action to retract the piston slowly. Avoid pushing directly inward on the spreaders when inserting or removing the tool, because lack of initial pressure can prevent proper engagement. Also consider that forcing uneven pressure may damage or misalign pistons, so check alignment before applying full force. 🛠️
Positive Aspects
The ratchet press offers a hands-on, mechanical approach without relying on hydraulics or specialized adapters, which can save time on standard brake jobs. The pair of extra plates increases compatibility with different caliper geometries and reduces the chance of marring the caliper surface. It is compact enough to store in a toolbox and straightforward to operate for routine maintenance or emergency roadside brake adjustments. 🔧
