Review on Enhanced FIRSTINFO Hydraulic Brake Bleeder Tool with Lockable 🔧 Hose and One Way Check Valve for Efficient Brake Fluid Bleeding by Robert Pierce

I bought this lockable bleeder hose to flush the brake fluid on my SBC equipped Mercedes. (SBC is an electronically controlled brake controller that uses extremely high pressure when it works. The Mercedes part (EHB adapter, #240589009100) is over $100.) This worked great for me and stayed with high pressure at the exhaust valve. Activation of the SBC block. By the way, to bleed the SBC system properly, you need the Mercedes Star Diagnostic System (SDS) or another suitable scan tool like the Autel MaxiDAS.
