The brakes on the Villager are as straight forward as the brakes on a 1965 Mercury. Only normal brake tools are required.
Conventional drum brakes.
This is as complex procedure. I suggest you buy a repair manual if it is not obvious to you, and you don't have experience.
It would be to your advantage to take your car to a Brake Repair Shop if you have to ask that question brakes are not something you should do if you do not have the skill, WBMS
You wreck the car !!!!!!!!!
The Mercury Mountaineer has hydraulic brakes, not air brakes.
You need to buy an adapter harness. Do not cut into your wiring harness.
If you turn on the key and there is a light that says ABS, then it does. ABS was an option that year.b
The rear brakes are a conventional drum system. If you don't have experience working one them I suggest buying a repair manual or taking it to a shop.
ABS was an option on Villagers. If you have an ABS light that lights up when you turn the key on the dash, you have it. If not, you don't.
Which brakes are you replacing front or rear or all four It shouldn't cost more than $100 with out parts and labor Or you can do them your self it's not that hard at all unless your are doing the rear brakes which will require a special brake spring tool
