brakes squeak at low speed braking

I have only 3000 miles on my 2011 Evora NA. When i brake at low speed they squeak and at high speeds the is slight vibration in the steering when braking. any thoughts?

Squeak/squeal yes. Normal. Hitting the brake real hard once in a while helps. Nature of them. Brake later in your stop.
Vibration, no, not on mine. Feedback, but I wouldn't call it vibration.

thanks Lckitty. I am thinking about putting the car on jack stands and inspecting the rotors and brake pads..but with only 3K miles i don't think that should be necessary right?

You can apply some brake squeel reducer on the back of the pads.

re: Brake Squeel

All disk brakes squeel. Some more than others. There are many cures:

1. Anti squeel compound... messy.
2. Anti-squeel shims.
3. Braking harder or more often to heat up the pads and polish them a bit.
4. Braking harder while reversing (i.e. press gas and brake at the same time). Again may take some varnish off the pads.
5. Harder compunds will squeel louder than soft ones. All compounds soften with temperature. Hence the brake warming trick. Either drive with one ffot on brake and one on gfas for 2 to 3 mins or fins an empty place and make 5 stops from 40 to 60 mph in a row....

Good Luck! I run race compounds on my daily driver M3. They squeel like stuck pigs when cold.

Unless you are occasionally standing on the brakes for aggressive stopping from say 75+ mph, the pads are just glazing. You need to heat those pads up and burn off the glaze. That will get rid of your squealing.Its a sports car. Don't drive it like a Prius!

A vibration to the steering caused by braking usually points to a warped rotor.

Mine squeaks a lot....when the brake is full of dust
Brought it to Brown Bear today and washed it clean, now it doesn't squeak. Although yes it still squeaks from time to time, and I was told that it's normal because of the racing pads.

You will not warp these rotors. What you will do is get substrate buildup from a pad contacting a rotor, say being parked after a wash etc and then not being "cleaned" off properly. Happens every time rotors get wet.

+1

The OE pads are also a little noisy when out of their operating temp range (*cold*). It's not unique to the evora, similiar pads (Ferrodo DS2500) do exactly the same thing on other cars.

That's good to know, though I would be interested in knowing how the Lotus rotor escapes vulnerability going from extreme hot to cold (such as driving through rainwater) where other manufacturers don't. I had lousy luck with Porsche rotors warping driving in stormy conditions in Florida.

I bet you dollars to pesos that you didn't warp those either. Pad transfer is the likely cause for the shuddering that you encountered. "Normal" brake rotors are cast iron and won't warp -- in the conventional sense -- at the temperatures that we subject them to.

Pretty good stuff! That's surprising from my perspective because the Porsche dealer put the rotors through rigorous testing before replacing them at no charge. I was at around 8k in mileage at the time.

Easier to replace than to resurface and they get to charge Porsche more also. Dealers love to hose the manufacturer

Porsche (as in the factory) doesn't believe in turning cross-drilled rotors. They just toss 'em out and replace. IIRC it has to do with an inconsistency in thickness.

Turning to me , is heavy duty, I meant that 1/1000th to clean them up.

Yes what is said, normal brake bedding operation is to transfer some pad material directly onto the disc's. Improper break in (i.e. low heat) causes uneven dristributiion of transfer material, resulting in unevenness and vibration. Cure, re-bed to an approved method, normally some ten medium brake pressure slow downs from 60 to 30 ish mph is to heat up, then some 10 more serious, below abs threshhold 60+ to 20 slow downs. Do not come to stop will brakes as it will build a ridge of pad material, drive lightly to cool brakes before stopping.

I think I follow this. What you're saying is improper braking at low temps is a big contributor to uneven wear, though I'm uncertain what it is that constitutes improper. The fix is to get the car up to 60 and brake hard to 20 but to not come to total stop until the brakes are allowed to cool for a period of time. Am I following you?
