Breaks Squeeking

[Marc]

Guys....2 issues on my 93 E36 325is

- I have 2 new Zimmerman cross drilled rotors and factory break pads in the front...

ever since I installed this combination the car "skreeches" from the front when I
break....what can be causing this?

- Also I installed a cone air intake and connected the thermo switch to the 2 tubes one of which has coolant.........right after I get a computer reading that my coolant level is low everytime I shut my car off......maybe the tubes are reversed? or bad coolant level switch?

my coolant sensor is picky as well, just check your resivour and make sure its up to snuff. i have zimmermann cross drilleds as well. one thing you will notice right away is a more rough feeling when you brake. but there should be no squeek. if your pads are good to go then maybe there is just build up on your rotors and pads. if that is the case get going and apply very FIRM brake pressure, and then do it again. i'm talking like 70mph-30mph and by firm i mean just shy of anti lock. that'll get 'em clean. but you may want to check to make sure your pads aren't dead.

To add to frolf's stuff...

How old are your pads? After about 500 miles you should Bed the pads. Going from 60mph to zero quickly (shy of anti-lock). Do this 2 or 3 times, then your pads should be good to go.

I've tried that with no luck....funny thing is this started happening with new pad and rotors in the front......the mechanic tried to quiet them down but it came back.....

Did he put anti-squeal lube on the new pads and calipers? It helps to dampen the vibrations that cause the squeal.

I dont know...but wouldnt that be temporary?....can I do this myself?

 

[Kirby]

It's basically a high temperature, silicon based lube that you put on before reassembly. You can do it yourself, but you have to dissassemble everything just as though you are replacing the pads.

where to apply the lubricant

Do you apply this directly on the brake pads...doesnt this make them slippery

 

[Big Daddy]

Apply it directly to the back side of the pads, not the braking surface. It works great and last the life of the pads if installed correctly.
