The parking brake decides the rear kit
Key takeaways
- Declare the parking brake first: an electric unit, a handbrake cable and a drum-in-hat layout lead to three different rear configurations.
- 17 inch and larger: rotor rows run from 300/330 mm at 17 inch to 355/380 mm at 19 inch.
- One rear set: 2 calipers, 4 pads, 2 custom hats and brackets, 2 hoses, 2 discs and 1 fluid depending on the model.
- Quoted, not assumed: compatibility may need an extra solution, so the quotation confirms it before anything is built.
Buyers usually treat a rear kit as the smaller half of a brake order, and then discover that the parking brake sits inside the decision. This brake caliper kit rear page therefore opens there: before the rotor row or the bracket is discussed, the file has to say what holds the car on a slope when the driver walks away.
What the rear file has to contain
Rear upgrades are more sensitive than most buyers expect, because the same model name can arrive with different hubs, offsets and hose interfaces.
| Item | Why the rear review needs it |
|---|---|
| VIN, market and model year | The same badge can leave the factory with different rear hardware in different markets |
| Parking-brake type | Electric, cable-operated and drum-in-hat layouts each change the parts list |
| Wheel diameter, width and offset | Places the rim over the caliper before a rotor row is fixed |
| Original rotor diameter and thickness | Sets the starting point for the 300, 330, 355 and 380 mm options |
| Hub photographs | Feeds the disc hat, centre bore and mounting pattern that will be cut |
| Photographs of the rear brake assembly | Shows the actual caliper, bracket and hose arrangement on the car |
Rotor rows for 17, 18 and 19 inch wheels
Rows from the seller’s record, and the published rotor options run 300–380 mm. Each one is a starting point that still has to clear the wheel and the hub on your car, across a 17–19 inch window.
| Wheel | Rotor row | What gets checked |
|---|---|---|
| 17 inch | 300 mm or 330 mm | Barrel clearance and spoke path around the four-piston body |
| 18 inch | 330 mm or 355 mm | Rim width, offset and the disc position inside the caliper |
| 19 inch | 355 mm or 380 mm | A wider envelope, plus hose routing at full suspension travel |
Why the rear rows start smaller
Rear wheels usually carry less diameter than the front pair, and the parking-brake hardware sits in the same corner. A 19 inch rear wheel that swallows a 380 mm disc still has to leave room for the caliper body, the bracket and the parking-brake mechanism, which is why the template check matters more here than the number in the table.
Three parking-brake layouts, three answers
Electric parking brake
An electric parking brake is run by a control unit and an actuator, and it reaches the rear corner in one of two ways. One is a cable-puller system – the layout where a motor pulls the existing handbrake cable – and the other is a caliper-integrated unit – the layout where the actuator sits inside the caliper body. Both exist in production, and they are not interchangeable, so the file has to say which one the car carries.
Cable and drum-in-hat
Cars without an electric unit use a handbrake cable, and some of those run a small drum brake inside the rear disc hat. The kit’s parts list changes around whichever arrangement is fitted, and a rear caliper that ignores it will pass the fitment check and fail the parking-brake test.
The same principle covers the hydraulics. A rear kit changes the brake balance, hose routing and bleed order, so the installer’s release check on a rear axle is about the parking brake and the pedal as much as it is about the wheel.
What ships in one F50 rear set
One rear set carries 2 calipers, 4 brake pads, 2 hoses, 2 brackets and 2 rotors, with one fluid bottle where the model calls for it. The approved quotation confirms the list that actually leaves the factory.
- Calipers: the F50 four-piston rear pair.
- Pads: four pieces matched to those caliper bodies.
- Hats and brackets: two custom pieces cut from the confirmed hub and offset data.
- Hoses: two lines with the interface and banjo orientation agreed first.
- Discs: two rotors at the approved diameter and thickness.
- Fluid: one bottle where the product model calls for it.
Packing reference
The carton is listed at 45 x 45 x 45 cm and 20 kg, and both figures follow the rotor size and the parking-brake solution chosen for the order. They are rechecked before dispatch, and freight is quoted separately.
What this page will not claim
The record refuses two tempting shortcuts. It does not sell by model name alone, because the same badge can carry different rear hardware, and it does not promise a universal rear fitment even though the field above this copy once used that word.
Three more limits stay in place. No stopping-distance, bias or temperature figure is published, because no test file exists for the configuration. No approval document is referenced, because none has been issued for this kit. And the F50 name is treated as the caliper family label the aftermarket uses, not as manufacture, sponsorship or authorization.
Two references were used while preparing this record: the Wikipedia article on the electronic parking brake for the cable-puller and caliper-integrated mechanisms, and the disc-brake article for the component terms. Neither approves an order. The record was last reviewed by the SteedLuxParts fitment desk on 2026-09-23.
How a rear order is quoted
From file to quotation
Once the parking-brake type, the hub data and the wheel envelope are agreed, one quotation fixes the rotor row, the hat and the bracket together. Production begins after the 30% deposit is received; the build takes 3–7 business days, delivery runs about 20–35 business days, and the balance is settled before dispatch.
Price steps, logo and markets
Tier pricing reads USD 399 a set for 1–9 sets, USD 358 for 10–49 and USD 299 for 50–199, with MOQ at 1 set. Colour and logo discussions follow the fitment review, and importers serving Africa, Kenya, South Africa, Ukraine, Kazakhstan, Russia and Europe use the same route with the confirmation completed before shipping.
The defect warranty stands at 5 years and covers manufacturing and quality faults, while wear, incorrect fitting and unauthorised changes stay outside it. Final terms are written into the quotation rather than left implicit.
Questions that arrive before a rear order
Which parking-brake type does my car use?
Look at the rear caliper and the workshop manual: an electric parking brake may be cable-driven or built into the caliper, and a car without one uses a handbrake cable, sometimes with a small drum brake inside the disc hat. Tell us which one you have before the quotation.
Will this rear kit fit my car?
It may, once the file is complete. We need the VIN, wheel size, original rear disc size, hub photographs and photographs of the rear brake assembly, because ordering by model name alone is how rear kits go wrong.
Can I run 355 mm discs on an 18 inch wheel?
Often, but not always. An 18 inch rim is only the first filter: spoke clearance, barrel shape and the space taken by the parking-brake hardware all have to be checked against the template.
Does an electric parking brake need extra parts?
Possibly. Parking-brake compatibility may need an additional solution, and it is confirmed by hand before quotation rather than assumed at the packing stage.
What is included in one set?
Two calipers, four brake pads, two custom hats and brackets, two hoses, two discs and one fluid depending on the model. The approved quotation writes the final list, and the front axle is not part of it.
What should be checked after the rear kit is fitted?
The parking brake on a slope, hose routing through full suspension travel, rotor centring inside the fixed caliper, bracket fastener torque, bleeding and leak inspection, then pedal feel and a road check before the car is handed back.
Rear-axle checks and the reference images
Three photographs sit below: a complete rear kit on a studio background, and two wheel-side views of a rear caliper. None of them was taken as a fitment record for a named car.
Open the review with the VIN, market and model year, the parking-brake type, the wheel diameter, width and offset, the original rear rotor diameter and thickness, hub photographs, photographs of the rear brake assembly, the destination country and the quantity. The reply names the rotor row, the hat and bracket position and the price for the rear set.
