A brake caliper rebuild kit in Australia must match the caliper type, piston size and mounting design. Depending on the application, a kit can include piston seals, dust boots, caps, bushes and rubber grease. Side coverage varies: a Genuine Nissan Y60 GQ front kit for twin-piston calipers contains parts to rebuild two calipers.

Choosing a brake caliper rebuild kit by vehicle name alone can leave you with the wrong seals or an incomplete set. Worn seals or corrosion in the caliper bore can cause leaks, while damaged slide-pin boots can let dirt in and cause pins to seize.

This guide explains what kit components do, how to match a kit to your vehicle and how to tell whether it covers one or both sides. You’ll also learn what to look for in rubber grease and which fitment details matter when selecting brake parts.

Included seals, boots, caps, bushes and rubber grease

Kit contents vary by caliper design. Compare each seal, boot, cap and bush with the component it will replace.

For a rebuild, use the matching kit, suitable hand tools, cleaning supplies and high-temperature brake grease designed for slide pins. This helps prevent rubber parts from swelling.

Warning signs include fluid leaks, damaged boots and slide pins that seize after dirt enters. Aged seals, corrosion or pitting inside the caliper bore can also cause leaks.

Seal, boot, cap and bush contents

Piston seals sit inside the caliper bore and help contain brake fluid. Dust boots protect the piston area, while slide-pin boots keep dirt away from the moving pins. Some kits also contain caps, bushes, rings and rubber grease. Before selecting parts, compare the kit contents with the caliper’s seal and boot positions and its slide-pin arrangement.

Pistons and seal kit options

Some caliper kits include replacement pistons as well as seals; others supply seals and related rubber components. Check whether a piston is included, then compare its dimensions and design with the existing caliper. A seal-only kit will not replace a damaged piston. Corrosion or pitting inside the bore can also compromise sealing, so inspect these surfaces during the rebuild.

During selection and assembly, match the kit contents to the caliper’s actual layout: seals belong in their corresponding positions, and boots, caps and bushes should match the parts removed. Don’t assume a package of rubber components contains everything needed for the rebuild. Check whether it supplies seals only or includes a piston. Use high-temperature brake grease designed for slide pins to avoid swelling rubber parts. Apply it to the slide pins, rather than substituting another grease around rubber components. If a component doesn’t match the existing arrangement, pause and confirm the kit selection before fitting it.

Caliper repair kit selection and fitment

Match each kit to the caliper type, piston size and mounting design. The vehicle make and model alone don’t establish fitment. Compare the part number and application details with the installed caliper before choosing a kit.

Use these fitment steps:

1. Identify the vehicle, model year, engine and axle position.
2. Confirm the caliper type, piston size and mounting design.
3. Compare those details with the kit’s stated application and part number.

For example, the Genuine Nissan Y60 GQ front brake caliper rebuild kit is listed for TB42E models from 10/1991 onward. Check the kit’s listed part number against its application details before choosing it. The kit is specified for twin-piston calipers and contains parts to rebuild two calipers. Use those identifiers to distinguish this application from other Y60 GQ configurations.

Australian roadworthiness and brake-repair requirements depend on the applicable state or territory rules. A rebuild must restore correct brake function, and vehicle inspection requirements also apply.

Fitment errors can leave seals or mounting components mismatched to the caliper. Compare the old and replacement parts, including piston dimensions and mounting points. If the caliper design differs, don’t treat a similar vehicle name as proof of compatibility.

For broader brake component selection, browse brake system parts alongside the kit’s application details. Matching the part number and caliper specifications helps narrow the correct option for the vehicle.

One-side and two-side kit coverage

Kit coverage is stated as one side or two sides. This tells you how many calipers the kit covers, not whether it fits your vehicle. Front and rear applications also differ. Match the axle position and kit coverage to the repair before ordering.

Australian listings show why the wording matters. The 0275-J31F and 0275-P11F front repair kits are listed for two sides. The 0275-N15F front kit is also listed for two sides. By contrast, the 2175-CA2F and 2075-BR4R rear kits are listed for one side. The 1275-LANR rear kit is listed for two sides.

• Two sides: 0275-J31F, 0275-P11F, 0275-N15F and 1275-LANR.
• One side: 2175-CA2F and 2075-BR4R.

Use the listing’s stated coverage to work out how many kits the repair requires. For example, a one-side listing covers one caliper, so servicing both sides requires coverage for both calipers. A two-side listing covers two sides, but you still need to check the axle position and vehicle application. Side count alone doesn’t establish fitment.

Before choosing, compare the kit code, front or rear application, and stated side count. Keep those details together when matching the kit to the calipers being rebuilt. For brake components, browse brake system parts alongside the vehicle application and coverage details.

These prices provide a further comparison when checking one-side rear kit listings.

Frequently Asked Questions

What does a brake caliper rebuild kit include?

A kit’s contents are defined by its specific product listing, so use the named kit and application as your reference. For example, “Pontos - Major Caliper Kit Front Torana K1664S” identifies a major kit for a front Torana application. Treat the title as an identifier, not proof that all kits contain identical parts. Read the listing details before selecting one.

How do I find the correct brake caliper rebuild kit for my vehicle in Australia?

For a modified vehicle, identify the caliper itself rather than relying only on the vehicle’s original configuration. Look for the manufacturer’s markings or part identification on the installed caliper, then use that information to narrow the catalogue results. This is particularly useful if a previous owner changed the brake hardware or fitted a different caliper assembly.

Where can I buy brake caliper rebuild kits in Australia?

Ozi Auto Parts sells brake system parts through its Australian website. Its catalogue includes listings such as “Pontos - Major Caliper Kit Front Torana K1664S”. Use the exact product title to locate that listing, then read its application details before selecting it. This example is specific to its named application, not a general kit for other vehicles.

When should a brake caliper be rebuilt or replaced?

Rebuild the caliper when inspection shows it can be returned to service with replacement parts. Replacement is appropriate if the body is cracked or the mounting threads are damaged. If the original braking fault continues after a rebuild, don’t keep driving to test it. Have the brake system assessed by a qualified mechanic before using the vehicle again.

How much do brake caliper rebuild kits cost in Australia?

Prices vary by kit and coverage.
