* Socket wrench set: To remove the caliper mounting bolts. The size will depend on your specific van (check your owner's manual or a repair manual), but it's likely to be a 14mm or 15mm.
* Wrench (possibly open-ended or combination): This is sometimes needed to hold the caliper bracket while you remove the bolts. Again, the size will depend on your van.
* C-clamp or caliper compression tool: This is absolutely essential. You need to compress the caliper piston back into the caliper bore before you can remove the caliper. Trying to do it by hand can be dangerous and damage the piston seal.
* Jack and jack stands (or ramps): To safely lift the van and secure it for working underneath.
* Wheel chocks: Essential for safety, even if using ramps.
* Socket extension(s): You might need these to reach the caliper bolts comfortably.
While not strictly *required*, these tools are highly recommended:
* Wrench for brake bleed screw: If you intend to replace brake pads, you will likely need to open the bleed screw to allow for easier piston compression. If your system allows for a single person bleed, this isn't as crucial, but it significantly eases the process.
* Brake cleaner: To clean the caliper and surrounding area.
* Gloves: To keep your hands clean.
In short, you don't need any *super* specialized tools, but a C-clamp or caliper compression tool is non-negotiable for safety and to prevent damage. The rest are standard automotive tools.
