OK, rebuilt the master last year. The rear circuit just failed so the cylinder walls may have pits I can't see. I want a master with provision for both switches so the "OFYOGHYB" light on the dash will continue to work. I'm unwilling to spend near $300 for a genuine ATE master. This appears to be a new-to-the-market valid replacement from Raybestos. http://www.amazon.com/Raybestos-MC36423-Brake-Master-Cylinder/dp/B000C6ZYLW Anyone have any experience? Anyone know where there's one *IN STOCK* that will ship in less than 3 to 5 weeks after I make payment? This is my daily driver and I'm currently driving gently around town on the front circuit only. It failed last night. I verified it was a failed master and not a messed up wheel cylinder etc this afternoon when customers slowed down. I need to get this ordered tomorrow (well, today now -- Friday) and delivered/installed by next Tuesday or Wednesday so I can still at least consider driving to Denis' house. We got (are getting) quite a bit of rain finally. Thanks all, Gerald
