Disc brake cylinder (caliper) A

Disc brake caliper, marked with the letter A in the name. The mounting hole spacing marked in the photo is 63 mm – start choosing from that.

• The same photo marks 87 mm, 16,5 mm and 39 mm, and another one – 43 mm and 65,2 mm
• The maker did not write what each dimension measures, so we do not assign meanings to them – we compare number with number
• The letters HS are cast onto the gold-coloured body; the same letters are also cast onto the caliper marked with the letter D in the name, and onto "Disc brake cylinder (caliper) E", so this feature does not tell the products apart
• This one differs from the caliper marked with the letter D not by the hole spacing – it is 63 mm for both – but by the drawing numbers: 87 mm versus 85,6 mm and 43 mm versus 43,2 mm
• The caliper is replaced not because of wear, but when the piston sticks, fluid seeps through the seal, or the pad pin is broken; the pads themselves are a separate replaceable part
• Do not confuse it with the master cylinder: the caliper presses the pads against the disc, while a separate product feeds it fluid – the same category has "Foot brake master cylinder RZ-D002" and four more of its relatives
• Supplier code WI ZQ4102 – state it again when ordering

To be straight with you: there is no data on the piston diameter or the hose thread for this product, and the difference from caliper D fits within a millimetre and a half. Which specific model and which years it fits, the maker did not write, and we do not guess – write us your model and year. Before ordering, measure your caliper's mounting hole spacing, their thread and the disc thickness – or send us a photo: we will check it before you order.
