BCC Daimler Double Six 5.3 litre (73-93) brake calipers have been carefully designed and developed over time by our product development team in our modern R&D centre.
Using the proven BCC Knockhill design calipers are machined in our UK factory from Aerospace grade aluminium for strength and durability before being sulphuric anodised all over to prevent corrosion.
BCC cast calipers are finish machined from proprietary 500/7 Spheroidal Graphite (SG) Ductile Iron castings and are then Zinc Passivated plated to prevent corrosion.
The pistons and brake pad pins are made from Stainless Steel to prevent corrosion and ensure a long life of faultless operation. High quality, modern fluid and dust seals are supplied by British manufacturers of OEM automotive hydraulic seals.
BCC calipers are fastened together with high tensile Holokrome steel bolts certified to grade 12.9. Our kits are supplied with Copper/Nickel Alloy hard lines with Brass fittings and EBC Ultimax 2 pads (Other pad options are available).
All caliper kits are assembled in our Advanced Engineering facility. Every caliper is tested individually for leaks and a test certificate is produced upon completion. We can trace each caliper all the way through assembly and production back to the initial material production.
We carry out extensive testing of our calipers using 3d modelling techniques, destructive testing and on-car performance testing to ensure optimal performance.
- Made and tested in our own UK factory to ISO9001:2015 quality standards
High grade Aluminium, Cast Iron and Stainless Steel materials
- Modern style fluid and dust seals (no dust boots that fall apart!)
Copper-Nickel pipes, brass bleed nipple and feed unions
High grade Stainless steel pistons, pins and fittings to avoid corrosion
Sulphuric anodised in a choice of colours (alu) or Zinc Passivated (cast)
Bridge pipes are used instead of internal porting to keep the fluid cooler
- Extensively tested with great customer feedback
- Normal delivery 2 - 3 days (silver or black)
Each BCC brake caliper kit includes a complete bolt-on axle set, comprising a pair of BCC 4pot calipers, EBC Ultimax brake pads (including pins, clips and springs), bleed nipples, bridge and feed pipes. Each kit is a simple bolt-on installation requiring no permanent modification to the vehicle and is completely reversible. [Vented kits for cars equipped with solid brake discs as standard, and drum to disc conversions will include brake discs and caliper mounting plates where applicable].
Main caliper body material specification:
Aluminium - 7075-T6 Aluminum anodised to MIL-A-8625, Type III, Class 2.
Ductile Iron Calipers - BCC cast calipers are finish machined from proprietary 500/7 Spheroidal Graphite (SG) Ductile Iron castings produced in an ISO:9001 UK foundry. Cast calipers are then Zinc Passivate plated to prevent corrosion.

Our calipers are designed to be a straight bolt-on replacement for your existing brakes with no modification to your vehicle. However please bear in mind that car production decades ago was far less consistent than today’s standards and minor differences are often found in classic vehicles.
We have been switching from e-clips to R-clips on our brake pad retaining pins to make assembly and changing pads easier (customer feedback told us e-clips tend to ping across the garage when fitting!). Some of our pins still use e-clips in which case we recommend using a small flat head screwdriver to push them into place.
It is crucial that brakes are fitted by a competent person, if you are unsure about any part of the fitting process please refer to a professional.
