Ke70 Ae71 Brake Booster Into Ke30 Ke35

[bruce]

Had a look at putting a AE71 brake booster into a KE35. The four mounting bolts to the firewall is compatible, but a bit of panel beating is required behind the strut tower underneath the brake booster, the lip on the firewall, and maybe the protrusion for the clutch cable mount. I'm planning on having a clutch master cylinder, but it looks like the AE71/KE70 booster will be in the way.

Has anybody gone though with putting one into a KE30/KE35?

 

I had a look through old forums and there was something on fitting a AE71 brake booster to a KE30 without any modifications:

The larger brake booster in the photo doesn't look like it is from a KE70/AE71. It looks to fit OK with enough room for the clutch master cylinder.

Does anybody know what it could be from? Or a booster that is of similar size and same bolt arrangement for the firewall and master brake cylinder?

I've ended up using a TA22 brake booster. Didn't really want to start banging the firewall and strut tower of a good car to fit a KE70 brake booster. The TA22 brake booster is bigger than an early KE30 one, and slightly bigger than the later KE30/KE55 one. I think the TA22 brake booster type was used in the TE3X corollas in Japan with the 2TC engine.

 

I did fit a KE70/AE71 master brake cylinder with the TA22 brake booster, and the brakes are too touchy now. Only a slight push on the brake pedal brings on the brakes really hard. Probably skid in the wet. The KE70 master cylinder has a 13/16" bore while the KE30 one has 3/4", so I think the KE70 master cylinder is moving too much brake fluid to the small brake calipers. Going to have to go back to the 3/4" bore, or go for bigger brake calipers with a strut upgrade.

I used a Datsun stanza, with pajero master, and the nissan pedal in my ke30,

 

Was a 7/8 and worked great
