For the last Two months ive been having a weird Brake problem

Sometimes when coming to a stop the steering wheel would shake badly and pull left to right a little.......I have had it to Brake guys and suspension guys but no one could give me an answer, anyway yesterday i had mum in the car with me and as we were slowing down turn the car shook really badly and kind of scared mum, so i thought stuff this its time to have a good look under the front end.....

all the suspension is ok as it is not that old checked to make sure all the bolts/nuts were tight...

So long story short look at the brakes on the drivers side first looked fine about 50% left on the pad. go to passenger side and the pads are like new pull the caliper of the slide no dust seal on the piston, got the misses to push on the brake pedal and no movement from the piston what so ever tried to push it back in but nothing....**** me

Lucky i have my TH parts car from the turbo conversion still in the Shed so off with its brakes and on to the TE did the whole lot Discs, caliper, slides, pads, hoses.....Changed the brake fluid bled the brakes took it for a run and **** ME the thing is like a Touring Car stops on a dime no more shudders even went to the places where it has done it before and nothing its like its a new car.....

Sounds more like warped disks to me, mine does this lightly on lightish braking from highway speed, push harder and it goes away

the shudder probably was the drivers side disc being warped due to it having to do all the braking.

i used to have to drive a morris minor panel van as a work car. it's brakes were shocking (drum all round, not vacuum assisted). 1st pump usually went to the floor, then it was push as hard as you could to stop. at traffic lights on a hill you had to wedge your leg between the steering wheel and the pedal to hold yourself there. and one time it had a kinked brake line on 1 of the front wheels, so the moment you hit the brake on rough roads it would nearly pull the steering wheel out of your hand and it would just dart off in any random direction. the boss wouldn't spend $1000 getting a datsun 120y disc brake conversion done.

once you have driven a car like that you know you are alive.

I have been having brake shudder for the last 8 months. My auto shop tells me Magnas are prone to this but the brakes are safe. They might be safe but the car is not a pleasure to drive any more.

I've had enough...tomorrow I get new rotors and pads. I'll let ya all know if this helps.
Cheers.

Depends allot on your driving style, pad selection etc. I know in my manual Magna (less reliance on brakes) I never once had warped rotors and any brakes shudder of any kind, and the brakes copped a work out.

If you like to do heavy braking slow down a touch earlier coming to a set of lights and slowly creep forward with minimal brake application, this stops the heat built up in the pads dissipating on one spot of the brake rotor (this is a major cause of warping). If you are a heavy braker and then just sit at the lights int he one spot the heat is dissipating on once half of the rotor, while the other side is cooling.

yeah and heat spotting give you the jitters too


dont know how that happened though ;)

although the rotors do look pretty cool when they turn blue!

you can see the blue tinge to my HD slotted rotors too.... all that heavy braking from high speed cant be good for it :D

I had my front rotors and pads replaced today.
Well worth it. The car now brakes like silky smooth. Absolutely NO shudder at high speed or lurching at low speed.
Going to go for a long drive on Sunday to enjoy my Magna.

BTW...cost was $227 at DMS Auto Care at St Marys. I totally recommend these guys. They do my services , rego checks and anything else I will need. (I am not affilliated with DMS.)

When I bought my Verada it had terrible brake shudder, a simple machining of all four discs made them perfect, no hint of shuddering at all.
