Wow. Replacing pads and rotors without bleeding? Somehow I thought bleeding was always the last step of any brake job.
Guity as charged. I was distracted by the "brake job."
No, there is no need to grease anything on an RX, or any of my current vehicles. The last time I used my grease gun was... let's me see... probably 30 years ago. Amazing, still have it in my garage....
if you don't open the fluid system then theres no need to bleed. if you press the piston in while cracking the bleeder then you MIGHT have to bleed if you let pressure off the piston and let air get in.
To answer your question, like 95% of cars dont need to be greased anymore, usually its only real 4x4s that have grease fittings and even thats going away slowly.
Anytime I saw a Zerk on a machine in a factory, you could guarantee the entire insides of the machine would be filled up with grease. Mechanics with their lube cart would come by and pump in half a barrel of grease…blowing out seals and making a general mess.
