A Renault caliper is one of the brake parts of your car. The calipers press the brake pads against the discs when the driver brakes.
Calipers do not need any particular maintenance. Over time they do show signs of wear around the piston joints which results in more space for motion. At this point your Renault's calipers do need replacing.n general if your calipers have too much space, you will be informed by your mechanic after an MOT.
At Mister-Auto we do recommend you always replace calipers in pairs to avoid wearing discrepancies between the left and right hand side of your vehicle. To find out which calipers are best suited for your Renault, please enter your vehicle details into the search engine.
