Adria Prima 350 Caravan Brake Restoration Guide
Comprehensive practical guide to restoring the complete brake system on a 1989 Adria Prima 350 TD caravan. This workshop manual documents the full overhaul and commissioning process for drum brakes fitted to IMV axles, covering everything from initial assessment to final inspection and road testing. The guide walks you through identifying and characterizing original components—drums, brake shoes, springs, and tapered roller bearings—and tackles the real sourcing challenges when replacements are unavailable. You'll find detailed solutions for adapting parts to non-standard axle designs, with particular focus on the pre-production variant issues specific to this model: fitting 40 mm brake linings into original housings and adjusting wear compensation pushers correctly. Disassembly and reassembly are covered step-by-step with extensive photographs showing drum cleaning, bearing inspection and proper lubrication methods, careful component grinding for correct fit, and calibration of the automatic slack adjuster. The troubleshooting sections explain how to diagnose and resolve parts compatibility problems when working with obsolete or poorly documented axle configurations. Written for restorers and caravan enthusiasts tackling vintage braking systems, this repair manual provides proven methodologies for achieving reliable braking performance on older caravan equipment.
