Tried to replace pads/rotors today. Humbling experience, just don't have the strength to do that any longer. I've done pads/rotors a dozen times but just couldn't get it done today. Broke a tool, spent an hour finding the right wrenches, bought a new breaker bar because the tire place over-torqued the lug nuts, and just couldn't get the leverage to get the caliper brackets off so I had to put it back together and call a local shop for an appointment tomorrow.
My front pads are only about 1/2 done but I have some steering wheel shake at light to moderate brake pressures. The wobble goes away when I push harder on the brakes and I suspect it's a hard spot on the rotors. I took the left side partially apart trying to do it myself today and if I slowly spun the rotor while lightly touching the face, there was one spot on the rotor face that felt different somehow, like maybe a slight bulge or different resistance against my finger. In any case, I have new delco blanks and pads ready to go on but I'm going to have to pay someone to do the work for me. Bummer.
Of course, it's a good time to replace the fluid while it's at the shop. Any suggestions or thought about Dot 4 or "Super Dot 4"? Does brand matter for a daily driver? Anyone heard of pentosin? At the auto parts store near me, Pentosin super dot 4 is like $16 for the bottle compared to prestone dot 4 for $10, so it's not like it's going to break the bank either way. I don't race so ultra high heat resistance isn't my primary concern. But I'm willing to pay an extra $5 if it'll last longer.
