Master Cylinder Bleeding - MK25
WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Vehicles that are not equipped with ABS also use this master cylinder, but in an effort to simplify the differentiation between early and late brake systems it is being referred to as the MK25 master cylinder.
CAUTION:
When clamping master cylinder in vise, only clamp master cylinder by its mounting flange. Do not clamp master cylinder piston rod, reservoir, seal or body.
- Clamp master cylinder in a vise.
- Attach special tools for bleeding master cylinder in the following fashion:
- Thread one Adapter (3), Special Tool 8822-2, in each outlet port. Tighten Adapters to 14 N.m (124 in. lbs.) torque.
- Thread a Bleeder Tube (1), Special Tool 8358-1, into each Adapter. Tighten each tube to 14 N.m (124 in. lbs.) torque. Flex each bleeder tube and place open end into mouth of fluid reservoir as far down as possible.
NOTE: Make sure open ends of bleeder tubes stay below surface of brake fluid once reservoir is filled to proper level. - Fill brake fluid reservoir (1) to the MAX level with Mopar® brake fluid or equivalent conforming to DOT 3 specifications. Make sure fluid level is above tips of bleeder tubes in reservoir to ensure no air is ingested during bleeding.
- Using a wooden dowel as a pushrod (2), slowly depress master cylinder pistons, then release pressure, allowing pistons to return to released position. Repeat several times until all air bubbles are expelled. Make sure fluid level stays above tips of bleeder tubes in reservoir while bleeding.
- Remove bleeder tubes (1) and adapters (3) from master cylinder outlet ports, then plug outlet ports and install fill cap on reservoir.
- Remove master cylinder from vise.
- Install master cylinder on vehicle. (Refer to BRAKES - BASE/HYDRAULIC/MECHANICAL/MASTER CYLINDER - INSTALLATION)
