FAQs
What vehicles are these brake bleed screws compatible with?
These M6 x 1 x 29mm bleed screws are compatible with many Audi, BMW, Fiat, Mercedes-Benz, Opel, Porsche, Saab, Seat, Vauxhall, and VW models that use this specific thread size and length. They are equivalent to Vauxhall/Opel OEM 542938.
What size spanner do I need for these bleed screws?
You will need a 7mm spanner. Laser Part No. 1551 is an example of a compatible tool.
Can I use these bleed screws on any car?
No, these bleed screws have a specific M6 x 1 thread size and 29mm length. You must confirm that your vehicle's brake caliper requires this exact specification. Using the wrong size can damage the caliper or lead to leaks.
How many bleed screws are in this set?
This set includes five (5) brake bleed screws.
What is the purpose of a bleed screw?
A brake bleed screw allows air to be expelled from the hydraulic brake system during maintenance. Removing air is critical for restoring proper brake pedal feel and braking performance.
Do I need to use any thread sealant?
Generally, bleed screws are designed to seal without thread sealant. However, always consult your vehicle's service manual for specific recommendations. Some may suggest a small amount of anti-seize compound on the threads.
What happens if I overtighten the bleed screw?
Overtightening can strip the threads in the brake caliper or damage the bleed screw itself, leading to leaks and costly repairs.
Troubleshooting
Bleed screw spins freely and won't tighten.
The thread in the caliper may be stripped. Inspect the caliper for damage. This bleed screw may not be compatible with your caliper's thread pitch. Double-check vehicle specifications.
Leaking around the bleed screw during bleeding.
Ensure the bleed screw is tightened sufficiently (but not overtightened). Check the condition of the bleed screw's sealing surface and the caliper's mating surface. A replacement bleed screw might be needed if damaged.
Difficulty fitting a 7mm spanner.
Ensure you are using a standard 7mm spanner. Some aftermarket or specialized tools may have slightly different dimensions. Confirm the bleed screw hex head is not damaged or deformed.

Setup, Compatibility & Care
Setup & Use:
- Ensure the vehicle is safely supported on jack stands.
- Locate the brake caliper and identify the existing bleed screw.
- Use a 7mm spanner to carefully loosen and remove the old bleed screw.
- Inspect the new Connect Brake Bleed Screw for any damage.
- Thread the new bleed screw into the caliper by hand to avoid cross-threading.
- Tighten gently with the 7mm spanner until snug. Do not overtighten.
- Connect a bleed tube and proceed with the brake bleeding procedure according to the vehicle's service manual.
Compatibility:
This set is specifically designed for vehicles requiring an M6 x 1 thread pitch and a 29mm length bleed screw. Refer to your vehicle's workshop manual or consult compatibility charts to confirm fitment for models from Audi, BMW, Fiat, Mercedes-Benz, Opel, Porsche, Saab, Seat, Vauxhall, and VW. It is an equivalent to Vauxhall/Opel OEM part number 542938.
Care:
After use, clean the bleed screws with a degreaser and dry them thoroughly. Store them in a clean, dry environment, ideally in their original packaging or a dedicated parts organizer, to prevent contamination and corrosion. A light application of anti-seize compound on the threads (optional, check service manual recommendations) can aid future removal.
