Second Hand Nissan Primastar Brake Caliper

The Primastar uses disc brakes with calipers on the front axle across all variants, so yes, front brake calipers genuinely exist on this model. Rear brakes on most Primastar vans are drum rather than disc, so if you need a rear brake component you are most likely looking for a wheel cylinder rather than a caliper. If you believe your van has rear discs, confirm this against your registration with the breaker before ordering.

The Nissan Primastar was produced as a single generation running from 2002 to 2014, sharing its platform with the Vauxhall Vivaro and Renault Trafic of the same era, so there is no separate second-generation model to worry about. However, there were running changes during that production run, and brake specification can vary with engine size and GVW rating, so a caliper from a 2003 van does not automatically swap onto a 2012 van without checking. Always confirm the specific part number against your registration with the breaker rather than relying on year alone.

Yes, engine size can influence brake specification because heavier-braking duty is often required on more powerful variants — the Primastar was offered with 1.9 dCi and 2.0 dCi engines, and these can carry different caliper sizes. When contacting a breaker, tell them your engine size as well as the year so they can match the correct unit. Do not assume a caliper from a 1.9 donor van will be a straight fit onto a 2.0 variant.

Yes, the payload rating matters on vans because higher GVW variants are often built with uprated braking components to handle the greater stopping loads. The Primastar was available in different payload ratings, so check the plate inside your van for the actual GVW figure and pass that information to the breaker alongside the year and engine size. Going by model name alone is not reliable enough to guarantee the correct caliper.

Yes, brake calipers are handed — the nearside (NS, left-hand side) and offside (OS, right-hand side) are mirror images of each other and are not interchangeable. Make sure you identify which side you need before contacting a breaker, as quoting the wrong side is a very common and easily avoided mistake. If you are unsure which is which, NS is the passenger side and OS is the driver's side on a UK right-hand-drive vehicle.

Trim level alone does not affect brake caliper fitment on the Primastar — the caliper specification is driven by engine size and GVW rating, not by whether the van is badged as a particular trim. You may find cosmetic differences such as wheel style between trim levels, but the underlying brake hardware is what matters. Focus on giving the breaker your engine size, GVW rating, year, and the side required rather than the trim name.
