Land Cruiser 70 Caliper Kit: GT6 Front or Rear EPB

One name, five wheelbases, and a change under the front end

Anyone selling brakes for this vehicle sells them by year band, wheel stud count or a caliper code, and there is a reason for that: one model name covers five wheelbases, a front end that changed in 2007 and engine families that run from a 1984 four-cylinder petrol to a 2023 2.8 diesel. The model record puts the family in production since 1984 as the replacement for the 40 Series, measuring 4,995 mm in short-wheelbase form and 5,245 mm long-wheelbase, at 1,790 to 1,870 mm wide and 1,955 mm or 2,070 mm tall. This page keeps that identification problem in front of the reader instead of starting with a caliper photograph.

A Land Cruiser 70 caliper kit from this page is quoted per axle, and only after the build has been identified. Owners of an early car and owners of a 2023 build are reading the same page, so the order of work is the same for both: settle the vehicle, decide the axle, then choose a rotor reference.

Which 70 Series is in the file: RJ7x to GDJ7x

The record publishes no year band. It asks for the car, and the table below lists what settles the build.

The model record is where the year and code detail comes from: it lists the 22R four from 1984 through the 1HZ, the 1HD-FTE and the 1VD-FTV V8 to the 1GR-FE V6 of 2009 and the 1GD-FTV 2.8 of 2023, all under the Land Cruiser 70 Series record. That source describes the vehicle family, not this kit, and it cannot approve an order.

Front option and rear option are two different builds

The front option is a GT6 six-piston caliper, and a fixed caliper of that shape uses opposing pistons to clamp from both sides of the disc rather than sliding on guide pins. Six pistons is also the far end of a pattern the trade has followed from single-piston units through two- and four-piston bodies, so the front build changes the caliper type on the axle rather than swapping one sliding body for another.

The rear option is an electromechanical caliper with a parking brake function, and that makes it an electronics build as much as a hydraulic one: the parking brake reference describes an electronically controlled brake where an actuator applies the pads under the command of a control unit, produced either as a cable-puller system or as a caliper-integrated system.

A single set covers one axle, because the strip lists two calipers. A customer who wants both axles is quoted two builds, each with its own fitment record and its own approval. Mixing the two into one line item is how a quotation stops matching the parts that arrive.

Rotor references for each option

What one axle set carries

One axle set carries 2 calipers, 4 brake pads, 2 custom rotor hats, 2 custom caliper mounting brackets, 2 hoses and 2 rotors, with one brake fluid when it applies to the selected version. Our confirmed list is written onto the approved quotation and the packing list before anything is machined.

The site material record puts the caliper bodies, hats and brackets at 7050 aluminium alloy, with the discs listed as high-carbon cast iron. Unlike some records in this range, the packing figures here agree with each other: the carton is listed at 45 x 45 x 45 cm and the gross weight at 45 kg, and both are rechecked before dispatch.

What this page will not claim

No OE, OEM or interchange number is published, and the kit is not offered as a factory replacement part. No stopping distance or fade figure is published either: the record states that no fixed claim is made without configuration-specific test evidence and that buyers may ask for whatever test records apply to the quoted setup.

The electronics stay outside the promise. No direct connection is assumed for the rear option, and the record names the pieces that need a configuration-specific review rather than a VIN check: the controller, voltage, wiring, ECU, CAN communication, Auto Hold, diagnostic behaviour, manual release and parking hold.

Two hardware items sit in the same category. The master cylinder, booster, ABS and any load sensing proportioning valve need their own assessment, and a load sensing proportioning valve – the device that trims rear brake pressure as the load on the axle changes – is exactly the kind of component that makes a vehicle-specific hydraulic review necessary rather than optional. A spacer is treated the same way: it changes the wheel position and needs a separate safety and local compliance review instead of being called a fitment fix.

Family and design facts come from the Land Cruiser 70 Series record and the parking brake reference linked above, which describe the vehicle family and a hardware type rather than this kit. The vehicle data was reviewed by the SteedLuxParts fitment desk on 2026-09-23 after checking it against those sources.

How an axle set is quoted

Two clauses on the current page still disagree with the rest of it and are being corrected: a Kit contents paragraph states a 12-month warranty and a 10-to-25-day production window, while the warranty block, the warranty field and the delivery block state 5 years and about 20–35 business days. The written quotation is the version we stand behind, and it follows the 5-year and 20–35 figures.

Questions that arrive before an order

After fitting, and the reference images

Three reference images sit below: a kit laid out with the rear actuators in view, a rear caliper with its actuator motors in the foreground, and a car with the rear wheel off during a physical clearance check. None of them is a fitment record for a particular 70 Series.

Send the model code and production year, the market version, the VIN or chassis number, which axle is being built, the wheel stud count and PCD, the wheel diameter, width, ET and model, the inner barrel and spoke clearance in both directions, the requested rotor diameter with thickness and offset, photographs of the wheel face, barrel, spokes, hub and existing brakes, and the destination country with the quantity. We reply with the approved axle, the rotor row, the hat and bracket position and the price of the set.
