what tools and parts are needed for brakes on my 1998 buick lesabre custom?

if you have disc on all 4 wheels front half inch wrench to remove calibers,a c-clamp to push piston back into caliber, use old brake pad on piston to push back in.Put new brakes on and caliber , do this on both sides, pump brake pedal.For rear -if disc , you will need a special tool ,available at most auto stores, where front piston pushes in, the rear piston turns clockwise in, you have to put pressure on ratchet with new tool to get piston to turn.replace brakes ,be careful with caliber, as sometimes is hard to line up bolt holes due to emergency brake , when finished pump up brake pedal again, ps--this is very important- if you don't pump brakes- you will NOT have any.check brake fluid,and fill if needed.If drum brakes- take to local mechanic, as this type of brake work is complicated .hope this helps
