Revision as of 07:59, 6 October 2015

A Brake Booster was fitted to many disc-brake B210s, including most 1976-1978 models and all USA models. The booster was added to counter the increased weight of these models. It is a very small 4.5 inch diameter model. This booster is not a direct bolt-in for a (Datsun 1200) as the mounting points are different. It can be fitted to a Datsun 1200 with small modifications.

Overview

B210 (including later 120Y) models that use a brake booster 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.

album

The booster has a:

• Front Spacer is a thin (20 cm) aluminum adapter so that a 2-bolt vertical pattern Brake master cylinder can be fitted
• 4-bolt rear mounting to firewall
• Rear Spacer is a rectangular aluminum unit, about 45 mm thick. It fits between the booster and the firewall.

full

B310 vs B210 style

• B310 has horizontal bolt-pattern master cylinder, Booster M60 (6" diameter)

  

• B210 has vertical bolt-pattern master cylinder, Booster M45 (4.5" diameter, 5.5" overall)

  

Use in B110

The B210 and B310 booster mounts to the firewall with 4 bolts, whereas Datsun 1200 (B110) has only two bolts drilled in the firewall. The shape of the firewall also differs.

1. drill larger center hole in firewall
2. Make 4-bolt to 2-bolt spacer/adaptor to go between the firewall and the booster

   

3. OR Use B210 firewall spacer
   1. drill two extra mounting holes in firewall

      

   2. change pedal box to new style
