Hydro boost brakes awful sound after finishing motor swap
I have just completed a Oldsmobile diesel to sbc 355 swap and on my first start every sounded great but the first time I pushed my brakes in it make a grinding noise, and would go away when I let off, I’ve had the truck running about 10 times since then and would come on randomly at idle, now...- Ryanbrown36
