Brake caliper servicing on heavy commercial vehicles requires tooling that can transmit hammer-driven impact force to release seized fasteners while still providing controlled torque application during refit. The Govoni GO1317 is a Torx slogging brake caliper wrench from the M-series range, designed for the assembly and disassembly of brake caliper fixing screws on the front and rear axles of heavy vehicles.
The slogging design is the defining feature: hammer blows on the end of the wrench transmit impact force to the fastener, breaking the corrosion bond on seized screws that no amount of steady torque could release. This is the established technique for heavy vehicle brake caliper servicing where corrosion and high original torque combine to lock fasteners in place.
The Torx profile provides excellent torque transmission with low risk of fastener head rounding, which is particularly important on commercial vehicle caliper bolts where replacement fasteners may be expensive or difficult to source quickly.
All Govoni slogging caliper wrenches are equipped with a 3/4 inch square drive, allowing them to be used with a torque wrench during the clamping phase of the operation in accordance with the vehicle manufacturer's torque specifications. A laser-etched torque conversion formula on the wrench compensates for the lever extension of the slogging design — the formula must be applied to set the correct final torque at the fastener.
The tool eliminates the need to remove the steering control tie rod lever during caliper servicing, simplifying the workflow.
Overall product dimensions are 230 x 65 x 65 mm and the wrench weighs 0.6 kg.
Govoni is a specialist Italian manufacturer of professional commercial vehicle tooling, and the GO1317 reflects the brand's focus on purpose-built tools for heavy vehicle brake servicing.
Additional Information
- Allows for the assembly/disassembly of the brake caliper fixing screws when working on the braking system.
- Used mainly on the front and rear axles of heavy vehicles.
- Even the most stubborn screws are released with the blow of a hammer on the end of the wrench.
- All wrenches are equipped with a ¾" square drive that also allows clamping, in combination with a torque wrench, according to the manufacturer's instructions.
- Warning: pay attention to the torque conversion formula marked on the wrench by means of a laser (necessary because of the lever's extension due to the type of construction).
- It is no longer necessary to remove the lever of the steering control tie rod.
