I thought I might try to start a thread where I could keep all my sh!t together - ask my daft laddie questions, and once I get a picture hosting platform set up, post pics of the more crusty bits of my car.
I did introduce myself elsewhere, but for the purpose of this thread my car is a RHD, 4.0 Thor auto, 2000my. Base/economy spec, and currently only on about 78k miles. I bought it last December on about 73,000.
I recently asked a question about getting underneath the car safely ( https://rangerovers.pub/topic/1831-getting-underneath-a-p38-safely-and-the-reason-why ) to try and figure out what was causing a steering wobble. Now awaiting a bunch of parts to start tackling and tightening up the front end suspension and steering. As I say, I'll post pics of the more crusty bits once I get Imgur or the likes organised.
However...... and getting to my latest daft question....
On the way to work this morning ( short run - about 7-8 miles) no wobble to begin with, starts about half-way. On the way home, same story. So I thought I would rule out tyre pressures or a slow leak. Bend down to take the valve cap off the drivers wheel and the heat is just bouncing off it. You could 'touch' the wheel - but you wouldn't want to hold your hand against if for longer than an instant. The valve cap wouldn't unscrew properly because it was half-melted.... oh dear... Passenger side was warm - maybe a little bit warmer than I might have expected after an 8 mile run at town speeds, but nothing in comparison to the driver's side.
I've left it where it is to cool down, and then I'll put it into its carport.
I assume this is a binding brake caliper. This will be my first experience with the 'sliding' type calipers - previous things I've worked on (minis/Defenders) have been the fixed caliper/moving pistons type. So, I'm further assuming that the caliper is sticking on the pins that it's supposed to slide along.
The working theory is that I don't get the wobble when I start off because everything is cold - then as things warm up, especially with a sticky caliper, things start to bind. Having one brake acting on one side is generating odd behaviour, and maybe my steering wobble??
Does this all sound about right so far?
So, moving on to fixing this:
- am I likely to need new caliper components, or just to clean and lubricate the caliper slides?
- will the heat have damaged the wheel bearing??
- I suppose it's possible the disc might have warped (feckity feck) but I certainly haven't thrown water at it to cool it down or anything.
- is there any possibility this is not caused by a mechanical issue, but electrical/ABS sort of stuff? I've owned ABS cars before, but never worked on them (see previous comment about minis and defenders).
Having just dropped £400 on suspension components, the last thing I really need is to start rebuilding the brakes too!
Finallly, just for some light relief. If I put the car on axle stands to do all this, and pull the battery to put it on a trickle charge, does it really matter how long the car is disconnected? The reconnection routine will be the same after 3 weeks as after 3 hours?
I will appreciate any assistance and advice as always - keeping this old thing on the road will be a new learning curve.
