Adria Prima 350 Caravan Brake Restoration Guide

Comprehensive practical guide to the complete brake system restoration of a 1989 Adria Prima 350 TD caravan. This manual documents the entire overhaul process for drum brakes equipped on IMV axles, from initial assessment through final commissioning. The guide addresses key topics including: identification and characterization of original components (drums, brake shoes, springs, tapered roller bearings), sourcing challenges for unavailable replacement parts, and compatibility solutions for non-standard axle designs. Particular emphasis is placed on challenges specific to this pre-production model variant, notably the adaptation of 40 mm brake linings to original housings and adjustment of wear adjustment pushers. Disassembly and reassembly procedures are detailed with extensive photographs covering drum cleaning, bearing inspection and lubrication, component grinding for proper fit, and automatic slack adjuster calibration. This manual provides invaluable reference material for restorers and enthusiasts working with obsolete or poorly documented axle configurations, offering proven methodologies for troubleshooting parts compatibility issues and achieving optimal braking performance on vintage caravan equipment.
