How To Replace The Gravelbleeder Screw On Your Wrx

If you're looking to replace the gravel bleeder screw on your Subaru WRX, it's important to know the correct size to ensure a proper fit. The size of the gravel bleeder screw varies depending on the model year of your WRX. For example, the 2002-2007 WRX typically uses a 7mm or 10mm bleeder screw, while the 2008-2021 models use a 10x1.0mm screw. To determine the correct size for your specific model, it's recommended to measure the hex size of your existing bleeder screws using a wrench. If a 10mm wrench fits, you need 10mm speed bleeders, and if an 8mm wrench fits, you need 7mm speed bleeders.

Speed Bleeder screws for 2002-2007 WRX

The Speed Bleeder brake bleeder screws are available for the 2002-2007 WRX model. These are designed with a built-in check valve, which simplifies the process of bleeding your brakes.

To determine the size of the bleeder screws your calipers require, you need to measure the hex size of your existing bleeder screws with a wrench. If a 10mm wrench fits, you will need 10mm Speed Bleeders. If an 8mm wrench fits, you will need 7mm Speed Bleeders.

The Speed Bleeder brake bleeder screws for the 2002-2007 WRX come in a set of four, along with four rubber dust caps.

WRX 2-pot calipers' bleeder screw size

The bleeder screw size for the WRX 2-pot calipers depends on the model year of your WRX. For the 2002-2007 WRX, the 2-pot calipers use a 7mm bleeder screw with an 8mm hex wrench head. For the 2008-2021 WRX, the 2-pot calipers use a 10mm bleeder screw with a 10mm hex wrench head.

To determine the correct bleeder screw size for your specific model year, you can refer to the following information:

• For the 2002-2007 WRX: The 2-pot calipers use a 7mm bleeder screw with an 8mm hex wrench head. This information was confirmed by multiple sources, including measurements made by WRX owners and inquiries to the Speed Bleeder company.
• For the 2008-2021 WRX: The 2-pot calipers use a 10mm bleeder screw with a 10mm hex wrench head. This information was provided by Oakos, an online retailer of Speed Bleeder brake bleeder screws.

It is important to note that the thread size of the bleeder screw may be different from the size of the hex wrench head used to tighten or loosen it. The thread size refers to the diameter of the threaded body of the screw, while the hex wrench head size refers to the size of the hexagonal recess that the wrench fits into.

When upgrading your brake calipers, it is essential to use the correct bleeder screw size to ensure proper brake system function and safety. Additionally, it is recommended to refer to the specific instructions and parts provided by the brake caliper manufacturer to ensure a successful upgrade.

Subaru 4-pot calipers' bleeder screw size

The Subaru 4-pot calipers were first introduced on the 2000 and 2001 JDM STi, and they are now used by many Subaru Rally Teams in Open and Group-N classes. These calipers can be retrofitted to WRX models from 2002 onwards, improving braking capacity.

When it comes to the bleeder screw size for the Subaru 4-pot calipers, there seems to be some variation depending on the year of the WRX model. For the 2002 WRX, the bleeder screw size is M7x1.0, and some later models have both M10x1.0 and M7x1.0. If a 10mm wrench fits, it's the M10x1.0, and if it's too big, it's the M7x1.0.

For the 2008-2021 WRX models, the Speed Bleeder brake bleeder screws with a size of 10x1.0mm x 1.40 are recommended. These screws feature a stainless steel spring, ball, and brass retainer, and the threads are roll-formed for added strength and smoothness.
