Front brakes - identifying some components.

[zambo]

 

First off, I noticed on a set of calipers I seem to recall I took off a ‘74 model a decade back, that the caliper halves have numbers that don’t match each other nor the ones on my car (which I assume may be originals) for that matter. All of them have different numbers - both halves.

 

 

 

I seem to recall reading on here ages ago, that these halves were matched up as they were made at ATE so just tossing up to get them overhauled or do the ones on the car. Calipers aren’t exactly originality items after all.

 

But when I had my calipers hanging in the wheel well, I didn’t notice these things being present, which dropped out with the pads on the stored ones pictured above.

 

 

As these anti rattle plates or some such? My car didn’t have noisy brakes in the 14-15 yrs I’ve owner her, so are these essential?

 

Finally, the “22” on the side of this parts car master cylinder is the same as on my car - is that an identifier for bore size or just a casting number to ID the part.

 

 

Thanks as always.

RealOEM puts the RHD master as 20.64mm which is 13/16”. For some reading ATE’s master cylinders are actually imperial but they size them in millimeters. 

 

The anti squeal plates are aftermarket.

Thanks Simeon for the actual sizing.

 

So is the “22” just a model number perhaps and the MC may have fitted a few vehicles? I have looked online and seen one advertised for our cars (Jaymic) and it has a “20” cast into.

 

So not sure about it all actually ...?

 

For viewers north of the Equator (aside from those from UK) this is just about the RHD version obviously and probably will not align in anyway with ATE’s models for the LHD cars.

I was googling the part number and I notice that ECS Tuning in the States Have new ones in stock for $650 USD (certainly with the same part number). They just describe it as a ‘Euro’ master cylinder. 

 

I think they were also fitted to the CS coupes as I am pretty sure the whole RHD pedal box came from them.

The cast number on the master is usually the bore size.

 

The caliper half numbers are just casting identifiers,

nothing more.

 

I always figured the inch brake dimensioning was something

painful in British or US import law, and it was easiest to

just use inches on all versions.
