2009-2021 Lotus Evora Brake Job Tools and Torque Specs

By Core Brake Parts Tech Team — Circleville, OH warehouse

A Lotus Evora brake job is a pad-and-disc service on AP Racing four-piston fixed calipers at all four corners, clamping 350 mm front and 332 mm rear ventilated cast-iron discs on the original V6 cars. You need basic metric hand tools, a torque wrench, a piston spreader suited to opposed-piston calipers and fresh fluid. Lotus publishes the fastener torque values in the Evora service notes, and those are the numbers to use; this guide covers what to have on the bench, how the job goes and which parts fit which years.

How the Evora brake system is built

The Evora does not use the sliding single-piston calipers found on most road cars. According to the SELOC technical wiki, every Evora V6 runs AP Racing four-piston calipers front and rear, with a servo-assisted, track-tuned four-channel ABS system. Sport Pack cars got cross-drilled discs, while non-Sport Pack cars got plain ventilated discs of the same size. Caliper color tells you a little about the car: Sport Pack calipers were black before model year 2012 and red from MY12, and entry-level cars left the calipers unpainted.

Because the caliper is fixed and the pistons oppose each other, pad changes are simpler than on many cars: the caliper usually stays bolted to the upright while the pads come out of the top after the retaining hardware is removed. Disc replacement is where the caliper has to come off.

The rear thickness figures come from a rotor maker's listing for the Evora and Evora S S1 rear disc. Always confirm against the minimum thickness cast or stamped on your own disc, since later Evora variants changed the brake package.

Tools you need for an Evora brake job

• Lifting: a low-profile floor jack and four stands. The Evora sits low, so check jacking points in the owner's handbook before you lift.
• Wheel removal: the correct socket for your wheel nuts, plus a locking-nut key if fitted. GTE-style center-lock wheels need the dedicated center-lock tool and procedure.
• Metric sockets and wrenches: for caliper mounting bolts and pad retaining hardware. A set of quality metric hex bits and Torx bits saves stripped fasteners.
• Torque wrench: one that covers both caliper mounting bolts and wheel nuts. Guessing torque on a car with track-capable brakes is not worth it.
• Opposed-piston spreader: a flat pad spreader or caliper piston tool that pushes both sides back evenly. A C-clamp on one side of a four-piston caliper can cock a piston.
• Brake fluid and a bleeder kit: a one-person bleeder bottle or pressure bleeder, a clear hose and a sealed bottle of the fluid grade specified in your handbook.
• Cleaning supplies: brake cleaner, a nylon brush and a lint-free cloth for the caliper abutments and disc faces.
• Measuring tools: a micrometer for disc thickness and a dial indicator if you suspect runout.

Where the torque specs come from

We do not print a torque number here that we could not confirm from a published source. Lotus keeps those values in the Evora service notes. A 2013 Lotus service bulletin (number 2013/17) refers technicians to the Evora service notes section TDU for brake hose setting figures, and says the braking sections of the service notes also hold routing and clearance guidance. Those same braking sections are where the caliper bolt and related fastener torques live.

Three practical rules apply regardless of the exact figure:

• Torque caliper mounting bolts to the service-notes value with clean, dry threads unless the notes call for a thread treatment.
• Torque wheel nuts in a cross pattern with the car on the ground, then re-check after the first drive.
• Replace any bolt the service notes list as single-use, and any bolt with damaged threads.

Step by step: pads and discs

1. Loosen the wheel nuts, lift the car, set it on stands and remove the wheels.
2. Inspect the caliper, hose and hard line before you touch anything. Lotus bulletin 2013/17 stresses checking brake hoses, pipes and hydraulic units at every service and renewing any hose or pipe showing chafing.
3. Remove the pad retaining hardware and pull the pads. Note which way any anti-rattle clip sits so it goes back the same way.
4. Push the pistons back evenly with the spreader. Watch the reservoir level so it does not overflow.
5. For disc replacement, unbolt the caliper and hang it from the suspension so the hose carries no weight. Remove the disc, clean the hub face of rust and scale, and fit the new disc.
6. Refit the caliper and torque the mounting bolts to the service-notes value. Install the new pads and retaining hardware.
7. Pump the pedal until it is firm before the car moves. Bleed the system if the pedal is soft or you opened the hydraulics.
8. Refit the wheels, lower the car, torque the wheel nuts and bed the pads in with a series of moderate stops before any hard driving.

When you fit new hose routing or refit a hose, Lotus says to confirm clearance from other components with the suspension at mid-laden ride height, because the factory routing is set at that height to avoid contact through full suspension and steering travel.

Which parts fit which Evora

Front pad fitment is the part people get wrong. The early cars and the later supercharged cars use different front pad shapes, so match the part to your build year and engine. In our catalog, the EBC SR-11 sintered front pads for 2010-2016 Evora 3.5L and the EBC SR-11 sintered front pads for 2015-2021 Evora 3.5L Supercharged are separate parts for exactly that reason. The DBA DB1938RP race performance pad set for 2010-2015 Evora is another option for earlier cars.

For discs, the DBA 4000 Series T3 slotted vented front rotor for 2009-2017 Evora 3.5L and the DBA 4000 Series T3 slotted rear rotor for 2009 and newer Evora 3.5 Coupe replace the factory cast-iron discs. Browse all brake pads and brake rotors if you need another compound.

Race compounds such as SR-11 and RP-1 are built for track heat. On a car that sees mostly street miles they can be noisier and grab less when cold, so pick the compound for how the car is actually driven.

What to replace at the same time

• Pad hardware: retaining pins and anti-rattle springs wear and lose tension. Fresh brake hardware keeps new pads quiet.
• Discs: replace them in axle pairs if they are near minimum thickness, heat-checked or cracked around the drillings.
• Fluid: Lotus suggests replacing brake and clutch fluid every year. A brake job is the natural time to do it.
• Hoses: any chafed or swollen hose gets renewed, per the Lotus bulletin.

Frequently Asked Questions

What are the caliper bolt torque specs for a Lotus Evora?

Use the value in the Lotus Evora service notes, braking section. We do not publish a number we could not verify from a fetched source, and a wrong torque on a caliper bolt is a safety problem.

Do I need to remove the caliper to change Evora brake pads?

Usually not. The AP Racing fixed calipers let the pads come out once the retaining hardware is removed. The caliper only needs to come off to replace the disc.

What size are the Evora brake discs?

Original V6 Evora models use 350 mm front and 332 mm rear ventilated cast-iron discs. Later variants changed the brake package, so confirm by part number before ordering.

How often should Evora brake fluid be changed?

Lotus suggests replacing brake and clutch fluid every year, regardless of mileage.

Will early and late Evora front pads interchange?

No. 2010-2016 cars and 2015-2021 supercharged cars use different front pad part numbers. Check your model year and engine against the fitment on the product page.
