Gents,

Is it easy to remove/replace the front discs on a 93 Brooklands? I have done this on other cars BUT someone said it's a 4-6 hour job on these cars.

I have a shudder under braking and need to either turn or replace the rotors. Probably will do pads as well.

Has anyone done this?

Thanks.

Hi

If its any help
I had a shudder on my ss2 and rather than replace discs had them skimmed on car.
Yes you are right big bill for disc changes on these cars, so have a think about skimming discs if for occasional use.
So far a year up the line and great, when I researched skimming it is pretty normal in USA etc but not so in uk, my drive towards this was I had a 538 BMW with dodgy discs, took it back to non dealer garage, who had discs skimmed, no better, only because the discs had no run off in an older car, when they were sorted with on car disc lathe, PERFECT, It is strange has not taken off like USA. MMMMM Me thinks more money in garage for new disc fitting, good luck

Hello,

I live in France and I am not familiar with the concept of disc skimming. I am replacing my front disc rotors of my 1997 Bentley Turbo r
LWB, therefore I turned to Flying spares and Introcar. Although they offer top quality parts I think that their prices are a bit high. I would like to if it possible or advisable to use front brake rotors of the same sizes and dimension made by other manufacturers such as Bermbo, ATE, and so forth.

Cordially,

PS: I suspect that the European Union regulations should not accept skimmed or refurbished disc rotors

Brake discs may not be your problem. There are a few other things to look for and they may be adding to the pulsating pedal and all should be looked into.
1. Tire balance, loss of wheel weight.
2 Bearing wear
3. Disc should be checked with a dial indicator for run out.
4. Is there enough material to safely cut or skim the rotor?

Hi Frank,


You have certainly the 340 mm disc/ rotor.
Not sure you will find any alternative, except from ATE but I don't have the reference.

For the pads, very particular for 340 mm , only made by ATE, I may be able to help you if you need pads too.

Observations: NO safety stand or block to minimize risk of the floor jack failure.
Use a flare nut wrench on flare fittings, not open end
You did not pack the bearings, only smeared them, not good
12 pt socket is not ideal for rear rotor bolts
Use lock tight on caliper bolts
Brake pad pins should have been cleaned and pad ears lubricated for movement
Appears rotor was not cleaned of preservative before pads were installed

Hi Wraithman, thanks for comments. My answers below:

Observations: NO safety stand or block to minimize risk of the floor jack failure. THAT IS INDEED GOOD REMARK! SAFETY FIRST!!!
Use a flare nut wrench on flare fittings, not open end I AM USING FLARE NUT WRENCH JUST TO LOOSEN OR FIX = UNSCREWING IS FASTER WITH OPEN END
You did not pack the bearings, only smeared them, not good I AM NOT SURE IF I UNDERSTAND THAT. I REMOVED THEM FROM CLEANER JUST BEFORE ASSEMBLY AND LET THEM DRY BEFORE APPLYING GREASE.
12 pt socket is not ideal for rear rotor bolts BUT IT WORKS WELL.
Use lock tight on caliper bolts NOT ACC TO WORKSHOP MANUAL.
Brake pad pins should have been cleaned and pad ears lubricated for movement I AM GOING TO REPLACE PADS. THIS WAS JUST ASSEMBLED TO MOVE THE CAR.
Appears rotor was not cleaned of preservative before pads were installed NOT ON VIDEO BUT CLEANED WITH DEGREASING SPIRIT (WE CALL THAT TECHNICAL GASOLINE)

Awesome video, thanks for posting. Love to see how everything is put together. It looked like those calipers may have been leaking a bit. Did you consider that or was that residual grease from the oil seal.

Calipers were overhauled recently in US. I just checked pistons and dust covers and they were like new thus I trust what is stated on invoice from car service.

This car was well maintained. For example recently replaced steering rack, front hydraulic spheres and many other parts like gasoline pipe.

On the other side car service two times machined front rotors down to 27,6mm what is way too low from 30mm minimum thicknes! They never removed hub thus kept leaking oil seals. Grease was everywhere around hub and rotors. Calipers itself are not leaking. Maybe you can see some LHM spilled on calipers during assembly but not really leaking.

Offtopic: I do not know where to post this question but I wanted to ask following related to undercarriage. My 1993 Brooklands has all mechanical parts like hand brake mechanism and springs, sections where brake pipes are connecting etc. fully covered in some kind of grey grease. When I remove it then all metal parts are still beautifully galvanized and shiny. Is this something factory original or was it applied during some maintenance? Odometer shows 100k miles.

OP Here:

I did replace the pads/rotors and car stops great now. I was thinking of going back in and painting the calipers black all the way around, as they look pretty beat up.

Hi!
Thanks for the video!
I had a go at changing the front brakes on my 91 Turbo R today, but couldn't get the bolts that hold the disc on the bearing housing off.
Do you know what the correct size socket is? And maybe the size of the bolts too, as they could do with being replaced.

Thanks!

The head on those bolts are called "triple square". Some have used a 12 pt socket, but as always the right tool gets the job done.
