High-Temperature Silicone Caliper Dust Boots
TTSPORT High-Temperature Silicone Caliper Dust Boots are service parts that replace worn, hardened, torn, or missing piston boots on compatible TTSPORT street-performance calipers. Fresh boots help keep brake dust, moisture, road grime, and salt away from the piston bore area so piston travel stays smooth and seals last longer.
Why Replace Dust Boots
- Blocks contamination from reaching the piston and seal area
- Helps maintain consistent piston movement during apply and release
- Inexpensive insurance against a full caliper rebuild
- Recommended when boots are torn, hardened, missing, or damaged during caliper service
- Inspect during pad changes on high-mileage calipers, especially if the vehicle sees heat, dust, salt, or wet road conditions
Product Highlights
Function
Flexes with normal piston travel while helping seal the piston bore area against dust and moisture.

Installation Notes
- Inspect the piston surface and seal groove before reassembly. Replace pistons or seals if pitted, scored, corroded, or damaged.
- Clean the boot groove in the caliper body so the new boot seats fully.
- Use only brake-system-safe assembly lube where required by the caliper service procedure. Avoid petroleum greases that can swell rubber components.
- Do not stretch, pinch, twist, or cut the boot during piston installation.
- Bleed the system and confirm pedal feel, leak-free operation, and even pad retraction before driving.
Safety: Brake service must be performed by a qualified technician. Confirm the correct boot for your caliper series and piston diameter before installation.
Compatibility
These boots fit compatible TTSPORT street-performance calipers only. Caliper series, piston count, and piston diameter all affect boot selection. If you are unsure which boot you need, send us your caliper photos and we will confirm before you order.
When to Replace
- Replace if the boot is torn, hardened, missing, burned, or no longer seated in the caliper body.
- Replace if contamination has entered the piston bore area.
- Inspect piston seals if there is fluid seepage around the piston area.
- Replace boots during a caliper rebuild when pistons are removed for cleaning or seal inspection.
- Confirm piston diameter before ordering because one caliper series may use multiple piston sizes.
Frequently Asked Questions
Will these fit any brake caliper?
No. They are service parts for compatible TTSPORT street-performance calipers. Verify your caliper series and piston diameter before ordering.
When should I replace dust boots?
Replace them any time a boot is torn, hardened, missing, burned, no longer seated correctly, or when contamination has reached the piston bore area. They should also be inspected during caliper rebuilds and high-mileage brake service.
How many boots do I need?
One boot is required per piston. Count the pistons in your caliper and multiply by the number of calipers being serviced.
What lube should I use during installation?
Use only brake-system-safe assembly lube where required by the caliper service procedure. Do not use petroleum-based grease because it can damage rubber brake components.
Can I install these myself?
Caliper service should be performed by a qualified technician. Proper cleaning, seal inspection, piston inspection, boot seating, brake bleeding, and leak checks are required before the vehicle returns to service.
Need help confirming boot fitment?
Send your caliper model, piston diameter, piston count, and clear caliper photos. TTSPORT will help confirm the correct dust boot before you order.

Right size item
Size: Small, Color: Light Grey
Make sure you order the right size. I received Small size & not Large. My fault. But, it still fit ok, a little snug, yet it made me feel warm when I went outside. I will be ordering a large size in the near future. Some one else in the family will get the small size item.

Worthy value.
Size: Large, Color: Dark Grey
Good underwear has a price.
This is definitely worth the investment. Not a heavy warm, but definitely a good cold day layer. Wore them in the house as sleeper.
They fit like spandex with a fly.
