rda slotted rotors

mildxe · 21-08-2011, 03:07 PM

hi
fitted a pair of rda slotted rotors and rda pads to my nf fairlane is it normal with slotted rotors when breaking a bit heavy to feel sort of a knocking with slotted rotors or does this disappear after a while would have done less than 15 kilometers so far thanks

No - the knocking feel is not normal although I'd try a couple of hard applications from 100 km/h to ensure they are bedded in properly.

Cheers
Russ

the rda instructions say it takes up to 300 km of normal driving to bed them in properly i noticed soft pedal feel for the 1st 60kms of driving , and a little brake squeal when bedding , but by 100kms very smooth pedal feel . as russ says , knocking is not normal . with 15kms on your car it's way to early to tell . follow bedding in instruction , light braking , increasing speed , and braking time but dont brake hard for the 1st 100kms . or just drive normallyu and report back after 100kms of traffic driving

thanks guys have done some bedding in like said around the side streets before posting this ! not talking about real hard braking but reasonable braking almost feels like you feel the slots in the rotor or may be a under laying prob somewhere put new tie rod ends on as well had bit of slop in them !

still have a brake issue to sort out on it maybe master cyl pedal has long travel and you have to push hard on it had a fluid change bleed them up no better ! might as well have drums on all four wheels !was like it before new brakes went on too

you can feel and hear them under hard braking.

Was the long pedal issue there before you fitted new pads and rotors? If you pump the pedal does it firm up but then next application it is low again?

its had long brakes no real stopping power since ive had it. it dont pump up any better by pumping pedal . stand on brakes hard try pushing pedal through floor pan and hope ya can stop ! but in saying that its the only car ive had with abs but if by jumping on brakes i would think it would lock up for split second unlock like a pulse effect ! put it this way wont tow with it !! have driven it today and brakes seem to be improving from 1st post starting to get some bite and knocking noise is a lot less noticeable thanks to all that have replied
