Our Gardeners truckster had lost it brakes . Usually it's a leaking wheel cylinder . After topping up the brake fluid and pumping the brakes I couldn't see any leaks . I did notice the master cylinder leaking a little and figured it was by passing fluid internally . Over all a pretty easy job . Biggest part was bleeding the brakes afterwards .
Master cylinder is in a easy location to the right of the steering wheel . The reservoir is in a remote location under the engine bonnet .
Surprisingly it wasn't to expensive for the new part and was in stock at out dealer at Eastern Turf .
I started of by draining the reservoir by removing the rubber hoses on top of the master cylinder , then I loosened the lines with a flare nut wrench . The pick above shows to loosen the nut off the bolt , If you try to take the bolt side off you may wind up stripping the head . Remove the plate that locks the brake pedal shaft in place .
I just used a pair of vise grips and turned it as your pulling it out . Hopefully it's not seized . Once the pedal is out of the way you can remove the 2 bolts holding the part on the brake pedal plate .
The pedal should pull out of the master cylinder and drop out .
Just finishing removing the 2 brake lines .
I see this may not be the first time it has been changed . 2 different bolts holding the part in .
On installation I hooked the rubber hose up first and then the brake lines . It is easier to do it this way before you mount the new part in place . Gives you a little more wiggle room to get the lines threaded on .
I also cleaned up and put never seize on the shaft that holds the pedal in place . Before you start bleeding the brakes top up brake reservoir . Always bleed brakes from the wheel cylinder that is the furthest away from the master cylinder . In this case Right rear .. left rear...right front ...left front .Work your way around till the air is all out . You may need a helper for this or you can put a line on the bleeder screw into a small jar partially filled with brake fluid and then you can open the line and pump brakes till the air is all out . Bear in mind that you will have to keep an eye on reservoir level and keep it topped up .
Here is a pick of how the pedal shaft is locked in place .
