I've had a brake failure on my 1998 LC. The dealer's $6000 estimate to fix the problem is unacceptable. After reading the many helpful threads here, I'm thinking about buying part #47050-60010. This actuator assembly appears to include the master cylinder, motor and accumulator for $2200 new. It seems to me this is probably everything I'll need in parts except perhaps the ABS computer . Am I missing something? BTW, I have a diagnostic tablet to bleed the system. TIA for any help.
