Question 1

How to replace the Brake Master Cylinder on Scion xA?

Accepted Answer

Draining brake fluid should be the first step for Brake Master Cylinder replacement followed by cleaning any painttarcted surfaces with water. The first step requires the disconnection of clutch reservoir tube for M/T transaxle alongside the removal of air cleaner cap sub-assembly. The brake master cylinder removal process starts with disconnecting the level warning light switch connector then using Special Service Tool: 09023-00100 to unfasten the two brake lines from the brake master cylinder sub-assembly. Chassis workers should unfasten both nuts and exit the brake master cylinder sub-assembly. It is necessary to begin brake master cylinder reservoir sub-assembly work by extracting the reservoir stopper and then removing the reservoir including two grommets and separating cap as well as strainer. The installation process begins with applying lithium soap base glycol grease to both grommets which need to be mounted onto the master cylinder before attaching the cap along with the strainer. Install the brake master cylinder reservoir assembly while fitting the tank stopper into its groove between the reservoir and master cylinder. Inspection of brake booster push rod requires observing it without vacuum while depressing the brake pedal multiple times when the engine remains off. Position the accessory tool on the brake booster assembly after applying chalk to its tip. Inspect the space between the push rod and the tool using the device provided with new brake master cylinder sub-assemblies for a 0-mm (0 inch) size clearance. Users must employ Special Service Tool: 09737-00020 to both stabilize the push rod and modify the extending adjusting bolt length when the brake pedal stays depressed in correct configuration. The brake master cylinder sub-assembly receives installation onto the booster which requires two nuts torqued to 13 Nm (127 kgf-cm, 9 ft. lbs.) then the two brake lines should be reconnected using Special Service Tool: 09023-00100 torqued to 15 Nm (155 kgf-cm, 11 ft. lbs.) while the level warning light switch connector should be connected. Familiarize the clutch reservoir tube for the M/T transaxle before installing the air cleaner cap sub-assembly and filling up brake fluid. Complete the bleeding process by bleeding the master cylinder and brake line and M/T transaxle clutch pipe line. The final step includes monitoring the reservoir fluid level while inspecting for brake fluid leakages.

Question 2

How to install the brake master cylinder on Scion xB?

Accepted Answer

Installing the brake master cylinder requires first checking the brake booster push rod clearance with the vacuum off while checking the brake pedal using the accessory tool several times with the engine off. After applying brake master cylinder sub-assembly accessory tool with chalk mark the tip of the tool and set it on the brake booster unit to measure clearance at the push rod location which should equal 0 mm (0 in.). Use Special Service Tool: 09737-00020 along with a socket driver (7 mm (0.28 in.)) to adjust the push rod length when the clearance measurement is not specified. Suppose you place a new O-ring onto the brake master cylinder sub-assembly following its installation and the sub-assembly and wire harness clamp bracket with 2 nuts at 13 Nm (127 kgf-cm, 9 ft-lbf). The brake tubes must be fitted to the brake master cylinder sub-assembly while using a union nut wrench for installation at 15 Nm (155 kgf-cm, 11 ft-lbf) torque without the wrench or 14 Nm (143 kgf-cm, 10 ft-lbf) torque that requires the wrench to maintain alignment with the torque wrench. After placing the harness clamp onto the wire harness clamp bracket you must install the wire harness onto the brake master cylinder sub-assembly and connect the brake fluid level warning switch connector. The vehicle features manual transmission so users should link the clutch reservoir tube using a clip. The installation order consists of the air cleaner assembly, outer cowl top panel, front wiper motor and link, cowl top ventilator louvers for both LH and RH sides and the hood to cowl top seal, front wiper arm and blade assemblies for both sides and the windshield wiper arm cover. Fill the brake fluid reservoir then proceed to bleed the master cylinder followed by the brake line and actuator before inspecting the reservoir fluid level and searching for brake fluid leakage.

Question 3

How to disassemble the brake master cylinder on Scion tC?

Accepted Answer

The first step to disassemble a brake master cylinder begins with removing the stopper screw and master cylinder union and continues with taking off the 2 grommets from the master cylinder. Apply a vise to the master cylinder by inserting 2 aluminum plates after which you can remove the O-ring. Through the use of snap ring pliers the snap ring can be removed after pushing in the piston while taking care because brake fluid might escape. The first step involves pushing down the piston to detach the piston stopper bolt together with its gasket before taking the No. 1 piston directly from the master cylinder body without causing damage inside. Pull the No. 2 piston straight out from the master cylinder body by tapping the flanged part against wooden blocks until the end of the piston becomes visible. During this process be cautious to not scrape the interior.
