Bro, brakes are easy to diy. YouTube is probably by far your most trusted source of information nowadays for anything and everything. It beats the advice from trolls like us all. You don't need a whole lot of tools. You will need a socket, rachet, & wrench set however. Harbor Freight sells them for cheap. When it comes to jacks, jack stands, and wheel chocks, you can use your vehicle's own jack. Just support the weight of your vehicle with the tires in case your jack fails or tips over because it is not on level ground. Other than that be safe and save yourself some money. That brake job will end up costing you 1/5th to 2/5 of what they are charging. I personally recommend that you invest in all the right tools which will cost a lot and take up space in your home but it will pay off in the end. Also, you have to have a lot of family and friends who can help too. Just borrow their tools until you can get your own. I'm sure they are willing to help a brother out.
