What size Allen wrench do you need to change front brakes on a 2004 dodge grand caravan?

There's no single Allen wrench size that universally applies to changing front brakes on a 2004 Dodge Grand Caravan. The size depends on which specific bolts are used to secure the caliper bracket to the knuckle. Some use a 13mm or 14mm bolt, while others can use an Allen Key, commonly a 7mm or 8mm. It's very model-specific.

To know for sure:

1. Consult your repair manual: A factory service manual for your specific year and model Grand Caravan will provide the exact sizes and torque specifications.

2. Look at the bolts: Before you start, visually inspect the caliper bracket bolts on your vehicle. This will tell you the type of fastener (Allen key or otherwise) and the size.

Don't rely on general information. Using the wrong size could strip the bolt head, making the job much more difficult.
