405 22.2mm Mc

[daveyboyblack 1]

Hi All,

 

I've searched through and seen conflicting answers on this question. I've got standard 1.9 calipers all round and uprated pads/discs and fluid. My car needs a new MC fitted and I was looking to get a larger MC (partly to have shorter pedal travel, and partly as I may decide to upgrade the front calipers/discs at a later stage) so the garage has bought one from a 405 ABS model.... 22.2mm.

 

Has anyone actually used this one and had any success/issues? I saw a comment regarding the pin depth being different so they won't release correctly?

 

Cheers

Dave

I have had experience of this. I was in the same boat, i had freshly built my car but was running low on costs and kept the 1900 calipers, but had a spare 406 Mc, so chucked that on. The non ABS is 4 pots (simple bolt on for 1.9 205s) where as the ABS model only has 2. So you may create extra work for yourself using the ABS model.

 

The car stopped fine, just a reduced pedal travel which was great for blasting down the lanes. It ran like this for 16,000 miles and is going back as per standard as the car is getting sold.

Ive recently swapped to a 406 MC, though im running 266mm brakes on the front, i also ditched the rear compensators.

 

Theres a rod inside the servo, with a dome nut, and a locknut. These can be adjusted. The haynes manual gives a figure, i just checked mine was in spec and left it at that.

 

Everything was straight forward (for once!) brakes work fine, pedal is much better, no binding or anything once pedal is released.

 

But as Alastair said, the ABS ones only have 2 ports that ive seen. So would be easier to get a non abs one, rather than faff around makign connections etc.
