<br><div><br></div>Brakes are definitely a limiting factor in many vintage cars. One of the things that keep them vintage. The rules for the three clubs below essentially say - calipers of the same size and number of pistons, rotors ditto.<div><br></div><div>SVRA says - <span class="Apple-style-span" style="font-family: Arial; font-size: 12px; ">3.

drilled or grooved.</span><div class="column"><p><span style="font-size: 9.000000pt; font-family: 'Arial'">4. Alternate calipers or wheel cylinders must be of the same material, design and number of pistons
as the original component. There must be no increase in the frictional surface of the pads or shoes </span></p>

Updating from drum to disc will result in reclassification if eligibility timeline (e.g. 1960) is crossed. Lining and pad materials are free. Rotors may be drilled or grooved, but must be same diameter, thickness, and material as originally supplied. Modern aftermarket calipers are not permitted. </span></p><div>VDCA - <span class="Apple-style-span" style="color: rgb(153, 51, 0); font-family: Geneva; ">Braking systems must be of the same type as standard for the year of manufacture or as homologated by the original manufacturer for that year.
