Have i got ABS brakes on my 92 RRC Vogue SE - How to Bleed them?

[Baggy]

HI All,

I’ve had a couple of scary moments with the brakes on my 92 Rangie.

On two instances I’ve had to stop suddenly and she’s just kept going …or more correctly not pulling up like I’m used to and that’s coming from a 2Dr classic.

I was standing hard on the brakes ….. no pulsing … just a hard feel with no stopping .... and I’ve checked the brake pads (on all 4 wheels) ….they all look new with no leakage from any calipers.

I’ve done some research and I believe ABS brakes were introduced to RRC from 1990 onwards.
They also mention bleeders on the master cylinder and talk of hearing your ABS pump etc … but I have no noise ….no dash lights (understand that doesn’t mean anything) but no extra warning lights on the dash are a positive for me [bigsmile1]

I’ve checked under the bonnet (picture) enclosed and the brake master cylinder looks standard to me.

I’d just like to bleed the brakes … whats the standard procedure and do I need any special tools.


Cheers

They're normal non ABS brakes, RRC ABS had this hideous hydraulic lump where your booster sits. Disco's had normal remote ABS with a booster like yours. Now in your case, unless your pedal is dropping to the floor I'd say your booster is dying. Find a d1 booster and bolt that on instead. You can do it without undoing the brake lines, just swing the master cylinder out of the way. Oh and be absolutely sure that the o-ring seal between the master cylinder and the booster is present and correct before proceeding. Without it you won't get much assistance.

If your pedal is sinking, bleeding might do very little, often the master cylinder is stuffed and they are not rebuildable. Normal bleeding procedures apply to your system if you've opened a line.

And, after looking at your picture again, my guess is that someone else has already removed the factory ABS and fitted a D1 booster. It's a bolt in fit. The pipes near the firewall look very untidy compared to stock.

Thanks bee utey

Appreciate your contribution and knowledge on this forum.

I'll hunt out a D1 Brake booster and go from there.

There have been a number of non genuine changes under the bonnet.

I think the original (long time ) owner changed out those systems that became unreliable and expensive to maintain ... Air suspension ( now coils) and now ABS which I'm happy about.

I'm in the process ( when I get the time) to swap out the electric seats (non working) with same style manual seats which I've purchased.

All part of a long term plan as a tourer and my 2Dr as a Sunday driver .... Well that's the plan.

Cheers

ABS or not should make no difference to the booster. Non ABS base models were available right up to the end of D1 production. I've fitted a '98 D1 booster to a '92 RRC and a '95 D1 booster to a '94 RRC. Not 100% sure if every single one is exactly the same but you'll soon find out. Master cylinders on the other hand are different, AFAIK. Different number of outlets but you can probably plug excess ports with caliper bleed screws as they are the same thread.
