Inspect, clean, and lubricate (or replace) the brake caliper slide pins on a 2024 Tesla Cybertruck Cyberbeast. Proper slide pin function prevents uneven pad wear and caliper bind — critical given the Cybertruck's ~6,800 lb curb weight and high regen/braking forces.

Warnings

Tools required

Parts

• Caliper slide pin boots (inspect; replace if torn) × 1 — OEM Tesla Cybertruck caliper guide pin boot kit
• Caliper slide pins (replace if scored, corroded, or seized) × 1 — OEM Tesla Cybertruck caliper slide pin set

Fluids

• Silicone brake caliper grease (high-temp, rubber-safe)

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with the key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Disconnect the low-voltage battery. NOTE: Cybertruck uses a 48V LV system (not 12V) — locate and disconnect per Tesla Service Manual; use 48V-appropriate procedures.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage (800V on Cybertruck) and lethal.
5. If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
6. Enable Jack Mode (Controls → Service → Jack Mode) BEFORE disconnecting LV power, so air suspension is locked at service height.
7. Chock the wheels that will remain on the ground.
8. Loosen wheel lug nuts while the vehicle is still on the ground.
9. Lift the vehicle using Tesla-specified jack pad locations and support on rated jack stands.
10. Remove the wheel to access the caliper.

Procedure

1. 1

   Inspect caliper and slide pin boots
   With the wheel removed, visually inspect the caliper, slide pin boots, and pad wear. Note any torn boots, leaking grease, or uneven pad wear — these indicate the slide pins are seized or contaminated and must be replaced, not just lubricated.
2. 2

   Remove caliper slide pin bolts
   Using the appropriate hex/Allen socket, remove the upper and lower caliper slide pin bolts that secure the caliper body to the caliper bracket. Support the caliper as the second bolt comes free — do not let it hang by the flexible brake hose.
   ⚠Never allow the caliper to hang from the brake hose — internal damage to the hose can cause delayed brake failure.
3. 3

   Suspend the caliper
   Use a bungee cord or caliper hanger to support the caliper from the suspension upright or control arm. Keep the brake hose unkinked and routed naturally.
4. 4

   Extract slide pins from caliper bracket
   Pull each slide pin straight out of its bore in the caliper bracket. Carefully peel back the rubber boot at the bracket end without tearing it. If a pin is seized, do not pry on the boot — work the pin gently with twisting motion.
5. 5

   Clean pins and bores
   Wipe old grease off the slide pins with a lint-free towel. Clean the slide pin bores in the caliper bracket using brake parts cleaner and a nylon brush. Inspect pins for scoring, corrosion pitting, or galling — replace if any is found. Inspect rubber boots for tears, dry rot, or hardening — replace if compromised.
   ⚠Do not use a wire wheel or sandpaper on the slide pin shafts — this destroys the precision fit and accelerates wear.
6. 6

   Apply silicone brake grease
   Apply a thin, even film of silicone brake caliper grease to the full length of each slide pin shaft. Pack a small amount of grease into the inside of each rubber boot. Do NOT overfill — excess grease creates hydraulic lock and prevents the pin from seating fully.
7. 7

   Reinstall slide pins
   Insert each slide pin into its bore in the caliper bracket. Seat the rubber boot lip fully into the groove on both ends. Verify the pin slides freely in and out of the bore — there should be no binding or stiction.
8. 8

   Reinstall caliper and torque slide pin bolts
   Position the caliper over the brake pads and align with the slide pins. Thread both slide pin bolts in by hand to avoid cross-threading, then torque to specification.
   Torque spec

   Caliper Slide Pin Bolts35 Nm (26 lb-ft)

Reassembly

1. Reinstall the wheel; hand-thread all lug nuts before lowering.
2. Lower the vehicle until the tire just contacts the ground, then torque the lug nuts in a star pattern.
3. Fully lower the vehicle and remove jack stands.
4. Reconnect the 48V low-voltage battery per Tesla Service Manual procedure.
5. Exit Jack Mode via the touchscreen — air suspension will resume normal operation.
6. Before driving, pump the brake pedal several times until firm to seat the pads against the rotor.

Verification

• With the vehicle stationary, press the brake pedal firmly — pedal should be firm and not sink.
• Confirm no warning messages on the touchscreen related to brake system, ABS, or stability control.
• Drive at low speed (under 15 mph) in a safe area and perform several light brake applications. Listen for clunking, dragging, or pulling — any of these indicate a slide pin not seated correctly or a caliper bracket bolt loose.
• After a short drive, recheck wheel temperature by hand near (not on) the rotor — a significantly hotter wheel than its counterpart suggests caliper bind from a seized slide pin.
• Reminder: Tesla recommends brake fluid replacement every 2 years regardless of mileage — note the date if not already done.
• Reminder: Cybertruck wheels should be re-torqued after 50–100 miles of driving and tires rotated approximately every 6,250 mi.
