After 13 years with the original fluid, and having pedal problems when hot, it was time to replace the whole system except for the original metal line. I recommend replacing the master, slave and the original rubber insulated hoe with the stainless insulated hose. You may spend almost $200, but if you take it to the dealer, the labor bill would be at least $500 and with parts, $800. Also, before you do anything, flush the entire system with a cheaper DOT 4 than the Motul. The old fluid can be toxic to your new parts. And be sure to put the new master cylinder in a vise with the old reservoir and hose and "bench-bleed" the master cylinder (You Tube video). Attach the reservoir and hose to the new master cylinder while on the vise and install the master, hose and reservoir together in the car. You can bend the hose and reservoir to vertical to get to the fitting and screw it in. Same with removing the old master. Remove the reservoir and bend the whole thing vertical to remove the fitting. Reinstall the old firewall gasket on the new cylinder while on the vise as well.
