A booster will not improve the braking ability of the car. But you may want one so that it is a bit easier to press the brake pedal.

Contents

Overview

With the light weight of the 1200, you don't need one (the pedal effort is not high on a 1200). Note that even on heavy cars, a booster doesn't make the brakes stop the car sooner, but only makes it easier to press the pedal (although on many cars such a large diameter master is fitted, it becomes nearly impossible to press hard enough if the booster stops working) If your small brakes are locking up now, a booster will only make them lock up faster with less pressure on the pedal!

Factory Brake Booster was used from October 1989 in Sunny Truck.

See main article: Brake Booster
What follows is for swaps from other cars

Swap choices include:

  • Lancer LA/LB or B210 booster for easiest fit into a stock 1200
  • Mitsubishi/Chrysler Galant
  • B210 Brake Booster & cylinder, was fitted to many disc-brake B210s. In Australia, you can use a 120Y dual system master cylinder and a 180B (610) booster
  • B310 (1979-1982) booster and master cylinder (13/16 inch). Need to modify firewall mounting point as these have four bolts
    You may need to modify (lengthen/shorten) the rod that comes out of the booster. Use a depth gauge (bit of stick) and make sure that the booster rod sits nicely inside the master cylinder. The booster is exactly the same internals as the 180B booster. Any larger booster, and you've really got to start cutting into the strut tower. reference: Sunny brake booster
  • 260Z master cylinder (7/8 in diameter)
  • master and booster from a Toyota Celica on a 1200. mareospeedwagon had to drill holes in the firewall to mount it but it worked real well.

Mitsubishi Lancer 1970-1980

The Mitsubishi LA or LB Lancer booster with its master cylinder is a straight bolt-in, though you may need to drill a slightly bigger hole in your brake pedal to fit the new pin through. It will fit next to a clutch master cylinder.

LA Lancer (1970-1976), also known as:
* Chrysler Valiant Lancer (1973-1976)
LB Lancer (1977-1979)
* Dodge Colt (earlier Colts were Galants)
* Plymouth Arrow (coupe version)

If you use a Datsun master cylinder with the Lancer booster, you may need to dent the strut tower in a little in order for the booster to fit.

LA/LB Lancer brake booster bolts straight up to the firewall, and the brake pedal, all u need is to get some brake lines made up. It uses 2 holes to bolt to the fire wall by way of a factory aluminum adaptor bracket.

To use the Datsun master cylinder with a lancer booster, you probably have to do some machining work. The outside diameter of the Datsun part is slightly too big for the front of the Mitsubishi part. A friend of mine machined down the master cylinder, but now I'd get the Mitsubishi bit made to suit the master cylinder. The part I'm referring to is the alloy casting which bolts to the front of the booster, and that the master cylinder bolts onto.

B210 Booster

Some B210 (including later 120Y) models use a type M45 Master-Vac with 4.5 inch vacuum diaphragm. It is the same as the 610/180B booster except for a different vacuum hose fitting. It can be fitted to a Datsun 1200 with small modifications.
