(Difference between revisions)

Revision as of 06:13, 18 July 2008

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.

The booster has a:

• 4-bolt front with a thin (about 1 cm thick) aluminum adapter so that a 2-bolt vertical pattern Master Cylinder can bet fitted
• 4-bolt rear mounting to firewall
• Spacer is a rectangular aluminum unit, about 2 inches long. It fits between the booster and the firewall.

B310 vs B210 style

• B310 has horizontal bolt-pattern master cylinder, Booster M60

  

• B210 has vertical bolt-pattern master cylinder, Booster M45

  

JDM

JDM B210s of GX and GL trim from April 1975 were fitted with Disc front brakes. A brake booster was standard for GX, optional with GL. The booster is a very small diameter, the M45 Master Vac, same as used in the 510 and 610.

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
