Retraction type: Compresses two push-back pistons together

Research-based review

QUICK VERDICT

A brake-caliper piston tool for suitable push-back applications. Check the caliper’s retraction method before choosing this tool, particularly where wind-back or electronic parking-brake procedures apply.

Our take

The 25750 is worth considering when you regularly service compatible calipers with two pistons that push straight back. Its simultaneous compression arrangement is the meaningful feature. It is not a universal rear-brake tool, and the vehicle’s retraction and electronic-parking-brake procedures must be identified before purchase.

Best for

Compatible dual-piston push-back calipers where the specified procedure permits compression using the inboard pad.

Skip it if

The piston must rotate, an EPB service routine is required first, or the caliper needs investigation rather than increased force.

Pros

Compresses two push-back pistons together
Hand-operated squeeze mechanism
Uses the inboard pad to distribute load

Cons

Not a universal wind-back tool
Does not place an electronic parking brake into service mode
Requires a suitable caliper and pad arrangement

Why compress two pistons together

Lisle describes a tool that uses the inboard brake pad to distribute force while compressing two compatible pistons together. That is different from pushing one piston while leaving another free to move. The useful result is an arrangement suited to that particular caliper design. Confirm the tool can be positioned correctly rather than assuming every two-piston assembly offers the same access.

Identify the retraction method first

Some pistons push back; others require rotation or a vehicle-specific electronic service procedure. The 25750 does not cover all of those methods. Lisle 28600 addresses supported rotating-piston applications, but it also does not supply EPB service mode. Read the vehicle instructions before selecting either tool, because forcing the wrong retraction method can damage the assembly.

The hydraulic system remains part of the job

Piston retraction moves fluid and can affect reservoir level. Follow the vehicle procedure for the reservoir, fluid handling and any specified bleeding operation. Unexpected resistance deserves diagnosis; a compression tool does not establish that the piston, slides or hydraulic circuit are sound. This review is a buying assessment rather than a complete brake-service procedure.

A targeted addition to the brake kit

The 81850 thickness gauges help assess accessible lining thickness, while MV6840 addresses compatible pressure bleeding. They do not replace this compressor because their functions differ. An apprentice should buy the retraction tool required for assigned vehicles rather than a collection of overlapping products labelled brake tools. Check course or workshop availability before duplicating specialist equipment.

QUESTIONS & ANSWERS

Frequently asked questions

Does it wind rear pistons back?

Not as its verified function. It compresses compatible push-back dual pistons; rotating designs require a suitable tool and procedure.

Does it handle EPB service mode?

No. A compatible scan-tool routine or other vehicle-specified procedure may be needed.

Why is the inboard pad used?

Lisle describes using it to distribute compression load across the supported dual-piston arrangement.

Lisle 81850 — 81850 combination brake-lining thickness gauge set. Nine acetal gauges; Straight and offset access. Colour bands are screening aids; replacement decisions use vehicle limits and a proper inspection, not colour alone.
Mityvac MV6840 — MV6840 pressure brake and clutch bleeding system. Manual-pump pressure dispenser; 1.2 US gallon / 5 L capacity. Match the adapter, brake fluid and vehicle pressure limit. A generic pressure bleeder does not replace a required ABS scan-tool bleeding procedure.
Lisle 28600 — Disc-brake piston wind-back tool. Rotates compatible rear-disc pistons into the caliper; Used with a 3/8-inch drive ratchet and extension. Match the engagement face and required rotation to the vehicle. An electronic parking brake may require a separate service mode; this tool does not provide that function.
