smartManiacs Source: smartmaniacs.co.uk Topic: brake system bleeding Models discussed: 450 Solution status: unclear

Problem: Spongy brakes requiring multiple depressions to engage; unable to locate front brake bleed screws. Discussion of whether DIY brake bleeding is feasible or if professional service with pressure bleeding equipment is necessary.

Solution: unresolved

Key facts: - Smart Fortwo 450 models are equipped with ABS brakes - Pressure bleeding (not manual bleeding) is recommended for proper brake system bleeding - Air trapped in master cylinder or ABS unit may require component replacement rather than simple bleeding - When replacing master cylinder, introduce air into system requiring full circuit bleed - Never push wheel cylinders back without opening bleed nipple on ABS-equipped vehicles as this can damage master cylinder seals - Front brake bleed screw location not identified in thread
